Contrasting Theories of Color
There has always been an understood correlation between light and color. Color cannot be seen when there is no light,but if there is too much light the world will only appear white. Today there is an understanding of what it is that makes color and how light is the key to it. It is understood that an object appears to have a color only when its apparent color is reflected back. There is also a known correlation between the wavelengths of light and their apparent color. Along with the physics of color there is a greater understanding of the symbolic nature of color and how it affects the psychology of observers. Psychologists, artists, and therapists of all sorts have a greater understanding of the human perception of color because of the great thinkers of the past. To men who contributed to this greater understanding of color were Isaac Newton and Johann Wolfgang von Goethe.

In this essay, the author
- Explains the correlation between light and color, and the symbolic nature of color and how it affects the psychology of observers.
- Explains that isaac newton had a fascination with color and its relationship with light. he came up with multiple hypotheses to explain what mechanical properties of light caused the appearance of different colors.
- Describes how newton experimented with the use of microscopes and telescopes to manipulate rays of light.
- Explains how newton proved that prisms and mirrors do not change the properties of light and don't cause cause color.
- Explains that the sun's white light is homogenial, meaning that it is composed of all the colors of light. modern scientists refer to this feature as a monochroma.
- Explains that unlike his previous theory, he no longer postulates that the force of the particles hitting the eye causes the perception of color, but the inertia of these particles.
- Explains newton's decision to separate the spectrum of light into seven separate colors, red, yellow, orange, green, blue, indigo, and violet.
- Analyzes newton's theory of color, stating that white light is composed of all of the different particles and therefore homogenial. he created a particle theory of light that attributes color to the respective masses and inertias of particles.
- Analyzes how goethe challenged newton's theory of light and color in his paper zur farbenlehre.
- Explains that goethe's theory states that the appearance of the sky displays this phenomenon.
- Explains goethe's claim that a special type of turbid medium that results in the phenomena of an entire spectrum of colors is the prism.
- Explains goethe's theory that color is not a physical thing that exists on its own, it only becomes part of reality when it is perceived by people.
- Analyzes newton and goethe's contributions to the scientific, psychological, and artistic understanding of color.
Newton acquired many of these lenses and began to experiment with how they could manipulate rays of light. In one of his experiments he had a beam of sunlight pass through one of the prisms and observed a spectrum of light hitting the wall of a dark room. He continues to manipulate these experiments. In one he drilled a small hole into a board placed against a window and then placed a prism over the hole. He projected this beam of light onto a wall as well as on a white sheet of paper. This created a round white image with a sliver of blue around the upper rim and red around the lower rim. He performed another experiment in which he had a beam of white light pass through one prism which separated the different colors and then made it pass through an identical prism that was upside down, which turned the beam back into plain white light. Through these experiments he showed that light can be both decomposed and put back

- Sir Isaac Newton's First Law Of Motionexplanatory essayIn 1704 Newton actually composed the book on the refraction of light. Jazzily titled "Opticks," the work changed the way we consider light and color. Researchers of the day realized that rainbows formed when the light was refracted and reflected in raindrops, however, they didn 't know why rainbows were so beautiful. At the point when Newton initially started his studies at Cambridge, the normal theory was that the water some way or another colored the sun 's beams distinctive colors. Utilizing a light and a crystal, Newton tested by running white light through a crystal to separate it into a rainbow of colors. The crystal trick was nothing new, The crystal trick was nothing new. By mirroring the scattered pillars into another crystal, however, Newton reformed them back into the white light, proving that the colors were a characteristic of the light

Various people have claimed that how we perceive color is the same universally and cross-culturally. We essentially see what is visible to our human eyes through a very small chunk of what is known as the electromagnetic spectrum. Although people with normal sight perceive this visible section of colors the same way, there is more contemporary research which points out that the way we categorize and think about color is more complex then it is made out to be. In this paper, I aim to discuss how there is support regarding how different cultures and languages do affect the way we understand and think about color. However, I believe there is much more close studying and research needed in the future to make more exceptional claims involving color perception to conclude that it is either solely universal or reliably dependent on one’s culture and language.
In this essay, the author
- Argues that color perception is a unique topic that researchers have been examining for quite some time. various people have claimed that how we perceive color is universally and cross-culturally.
- Explains that jules davidoff, ian davies, and debi roberson conducted a study in 2000 that replicated older research studies. their research supports the idea of using color terminology and categorization.
- Argues that more research is needed to support the direct evidence regarding how we categorize color.
- Analyzes how dedrick (2005) explains that color categorization is not innate cross-culturally. roberson and kuehni's research shows that the number of fundamental color words has a negative correlation with how many groups we place these colors into.
- Analyzes how alvarado and jameson's (2005) study compared the amount of confidence when classifying color between the languages of english and vietnamese.

Usually nobody ever stops to think, “what if there was no color?” Color is seen by almost everyone so no one necessarily has to wonder what it would be like if color wasn’t there. However, philosophy professor James Landesman has provided a theory in which people learn color may really not exist. Although this seems like a shocking and even ludicrous proposal, his essay Why Nothing Has Color: Color Skepticism brings up many points that can lead anyone to doubt the existence of something so trivial.

- Analyzes how james landesman's essay why nothing has color: color skepticism brings up many points that can lead anyone to doubt the existence of something so trivial.
- Analyzes how landesman defends a view called color skepticism, that nothing has any color, neither bodies nor appearances, and rejects historically influential accounts of the nature of secondary qualities.
- Explains that it is possible for every living organism to perceive objects differently from how other living things see it. this difference is due to the multiple ways the visual systems respond to light.
- Opines that the main purpose of life is not to figure out the truth of what exactly colors a certain object is. living things have natural instincts to survive.
- Explains landesman's point that color itself takes no role in causing living organisms to see color. the reality of color consists of the impact of radiant energy on our nervous systems.
- Explains locke's theory of primary and secondary qualities, and landesman focuses on three major points.
- Explains that colors are spread over surfaces of objects and intimately connected to shapes and sizes. locke's view uses the concept of red in describing the sensation it causes.
- Explains that a color realist can claim that colors are emergent properties. emergent colors satisfy the prejudice in favor of color realism.
- Opines that landesman explained his beliefs of and defense of color skepticism.
- Concludes that there can be a lot more to the world than our senses lead us to believe if we make inferences based on what we believe.

Both of these theorist believe that when teaching diverse students, teachers need to see their students for who they are. Seeing your students for who they are, means you look past the color of your students’ skin and recognize their culture. According to Stubbs, when teachers look at their students equally, no matter the color of their skin, then the teacher is considered colorblind (2002). Being colorblind is not a great thing because we should not treat all of our students the same, since each student is different. It is important to see our students for who they are because our classes are unique. Instead, our classes represent a rainbow underclass. According to Li, the rainbow underclass is the representation of families who are culturally diverse and economically disadvantaged (2008). In order to meet these student’s needs, teachers need to think about the struggles that each student face.

The key to Newton’s experiment was a glass prism. According to the book, Isaac Newton (written by Gale E. Christianson), glass prisms were believed to have displayed the phenomena of the scale of light and give proof that the scale of light went from a bright red (color closest to white) to a dull blue (color closest to black). It was also believed that all of these colors were modifications of true white. To test this theory, Newton bought a glass prism “to try therewith the celebrated phenomena of colors” (More, 389). Newton took his prism to his upstairs bedroom and made sure that the room was completely darkened. He then positioned the prism on a table and drilled a one-eighth inch hole into the window shutter so that the light would pass through the prism at a specific angle and was projected onto a wall ("Newton and the Colour of Light"). According to the accepted theory of light, should light pass through a glass prism at that angle, the colors of the spectrum of light should be projected in a perfect circle. However, Newton observed that the colors were arranged into a rectangular shape and the pattern was wider than was predicted. Newton concluded that each color refracted at a different angle as it passed

Light, as perceived by humans, is simply electromagnetic radiation with wavelengths between roughly 380 nm and 740 nm. Wavelengths below 380 nm and above 740 nm cannot be seem by the human eye. Electromagnetic radiation with a wavelength just below 380 nm is known as ultraviolet radiation. Electromagnetic radiation with a wavelength just above 740 nm is known as infrared radiation. The sun, black lights and fluorescent lamps are all sources of ultraviolet light. Heat is a source of infrared radiation, which is how thermal vision works.

In essence, the earliest telescopes such as the one used by Galileo consisted of the glass lenses mounted in a tube (Jenny, et al. 12). Further, Newton discovered that when light passed through a lens, the different colors were refracted by differing amounts. In solving this problem of the chromatic aberration, Newton designed a telescope that used mirrors, rather than lenses, to bring the light to a focus. Further, the light from the object being viewed is collected by the concave primary mirror and reflected a smaller secondary plane mirror. Furthermore, the mirror is inclined at 45 degrees to the axis
In this essay, the author
- Describes the objectives of the laboratory experiment to design and explain the newton's telescope.
- Explains the angular magnification of a newton's reflective telescope, which is defined as the ratio of the image seen looking through the telescope to the object viewed with the unaided eye.
- Explains that for objects outside the focal point, an inverted real image is formed, and an erect virtual image will be the outcome. the refracted rays are traveling parallel to each other.
- Explains that the magnification equation consists of 1/0+1/f = 1 / i. the virtual image formed by the convex lens is negative, whereas f is positive for the diverging mirrors.
- Explains that the ray diagrams for the concave lenses inside and outside the focal point produce erect virtual images that are smaller than the objects.
- Explains that the equation behind the image formation is illustrated as 1/0+1/f = /f. the i is positive for a real image, whereas the 0 is normally negative.
