Colors and Dyes
What is color? Although we know it's in the visible spectrum, color is more complex than we think. Just like dyes and many other things, there is certain science behind it and the name of that science is called chromatics. With the technology we have today, we can pinpoint the chemistry of an object with a snap. So with color, we pinpoint the chemistry by studying wavelengths, the distance between two connecting peaks or troughs of a wave.
Light that reflects of an object is seen as color in the human eye. Color can be related to objects, light, and materials just by the way we perceive it. Color can also have effects on the human body or mood just by its wavelengths being reflected onto you by a light. However, color can only be seen within wavelengths of 400 nm and 700 nm which make up the visible spectrum. These wavelengths in the visible spectrum have frequencies ranging from 430 to 790 THz.
Out of the whole electromagnetic spectrum consisting of x rays, ultraviolet rays, infrared rays, microwaves, and radio waves, the visible spectrum is made up of the only rays of light people can see. Also, the way our pupils receive light affects how we see color because when the environment we are in or object we are observing is reflecting too much light, our pupils decrease in size so we don't take in too much light. In addition, when we are in an environment or observing an object that reflects little light, our pupils increase in size so that we are able to absorb more light so we will be able to see the color of our surroundings. Within the visible spectrum, the light that we see from an object is called complementary colors. Complementary colors are the leftover colors that we see after the light of t...

...e process that makes up another. In addition, it is one of the links to the past and helps improve lives today. It has helped create new technology that has improved healthcare, food, and transportation. Without chemistry, we wouldn't have a lot of the products we have today, including colors and dyes. With all the atoms, electrons, chemical properties, and energy around, chemistry has made sense of it. Chemistry has certainly made an impact on the world.

  • The Color-In-Context Theory: The Romantic Red Effect

    513 Words  | 2 Pages

    The pupil is where light can enter the eye. The iris is in control of the amount of light that actually goes through. The light reaches the lens, which alters the shape of it so the eye can focus on it. Light reaches the retina, which consists of cones and rods. Colors are saw differently based on their implied meanings, which to various psychological functions. The cones are responsible for color. The color red would have such an effect on people’s perception of others based on their production of affect, behavior and cognition. A sociocultural theorist would explain this effect by indicating that the associations with the color red are normal. When a student sees a plethora of red marks on their paper, they automatically think they failed the assignment. Biological theorist would best explain this theory by saying the color red helps them survive or reproduce. A man may be attracted to a woman more because she is wearing red. This attractiveness could cause him to find his mate and eventually reproduce. A behavioral theorist would explain this effect by saying the color red provokes pleasure and avoids pain. A person can associate red with romance and

  • How do different colors absorb and re-emit radiant energy?

    2025 Words  | 5 Pages

    For this discussion, I am referring to thermal energy, also referred to as heat. Heat is actually light, but it is a light that is invisible to us, or not in the visible portion of the Electromagnetic Spectrum. Infrared light is the heat that we refer to normally and is located just below the color red in the Electromagnetic Spectrum. Its name is literally its definition. “Infra,” which means “below,” then “red.” So, infrared, or “below red,” is below red on the Electromagnetic Spectrum. We can see things that do not give off their own light because of reflection. When a color reflects light, the light reaches our eyes and allows us to see the color. This means that if we turn the light off in the room, we cannot see the colors because they do not give...

  • Color

    Color is sensed when white light bounces off an object and is reflected into the eye. Objects appear different colors depending on what colors were absorbed and which were reflected. Color is "seen" by the rods and cones in the eye. Cones detect color and rods detect black, white, and shades of gray. People who cannot see colors properly are colorblind. There are many different kinds of colors and they are classified in many different ways (The World Book Encyclopedia p 818, 819).

    Color vision helps people recognize different colors and distinguish possible difference in their hue and saturation, offering information about the world through a nonlinguistic code (Neitz & Neitz, 2000, p. 691). Colors give an understanding of situations that humans could maybe not perceived otherwise. For example, a person with extremely red eyes can end up suffering of various diseases, such as conjunctivitis, which can lead to blindness if not treated. This is not to say that color vision is not an advantage in very basic situations as well: colors can be used in order to figure out whether food is general is spoiled or still good for

    One of the most important (and most interesting) conclusions of the biology of vision is that color is not technically generated by physical reality. Color appears to be a mental construct, and therefore, everyone views color differently. The rationale one is often given for the color of particular objects is the following: light consists of all colors. When light strikes an object in absorbs most of the wavelengths of light, but those that it reflects correspond to the color one sees.

  • Cataracts: The Difference Between Light And Dark

    315 Words  | 1 Pages

    Color depends on how much of the pigment melanin you have in the color part of your eyes. The more pigment the darker the eye color. The lighter the color is because of the less amount of melanin there is in the iris. Cataracts are the clouding of the lens that prevents light from entering. Double vision, decrease in vision, fuzziness, and blurriness could all be problems when bright light occurs. Causes of cataracts could be from smoking, diabetes and also excessive exposure to light. The function or purpose of the retina is to receive the light that the lens captures, turn the color of the light seen into neuro signals and send those signals to the brain for recognition. This is knowing the difference between light and dark. Floaters are

    Cones cells distinguish between different wavelengths of light, thus allowing us to see in colour. (Sparknotes 2016) This is why the colours were distinct during the light period. Since cones aren’t used in dim light, this explains why it was difficult to see colours in low light. Interestingly, since nothing categorically distinguishes the visible spectrum of electromagnetic radiation from invisible portions of the broader spectrum (reference), colour is a mere feature of visual perception of the observer. Thus, human experience of colour is subjective. This explains why I saw the sky as a bright orange as the sun was setting and my friend saw a darker

    There are a large quantity of English color words. According to etymology, they can be divided into two kinds, basic color words and object color words. The former are some words which are used to express the color of something originally, such as white, black, gray, brown, red, green, yellow, blue and purple. The latter are names of some objects initially, and anyone of them has a distinctive color. Later these words can refer to the characterized colors of the objects as well as themselves. For example, gold, silver, orange and so on. (¡¶Ó¢ÓïÉùÉ«´ÊÓë·­
