Color and temperature, how are they related? Are they related? To understand these questions several concepts must be understood having to do especially with light, the actions light waves can take, how color works, and how temperature works. Once having a good understanding of these concepts putting the pieces together to come up with an answer can be easier.
To begin transmission, reflection, and absorption are very important. These are all actions light waves can take. Light waves which mean heat. To start, transmission ties in with reflection. Transmission and reflection occur because "the frequencies of the light waves do not match the natural frequencies of vibration of the object." Transmission occurs when the object is transparent,

Color does affect temperature because different colors have different amounts of energy, which is what causes temperature. Depending on the energy of the color some attract light, which equals heat more than other colors. Color temperature is affected by its energy, which is affected by the colors' frequency and wavelength, so which colors get hotter faster compared to others? Examining an electromagnetic spectrum chart, colors in the range closer to red, have a longer wavelength, and lower frequency, which equals lower energy. Colors in the range closer to indigo on the other hand have a shorter wavelength, and higher frequency, which equals higher energy. Therefore colors like red attract light more slower, which means red colored objects take longer to get warmer versus an indigo colored object for instance.
Examples of other science fair projects similar to ones that have tested color vs. temperature are by using colored cloths. A thermometer was placed and at separate times different colored cloths were placed over the thermometer under a lamp. The temperature of each trials were taken, and the color and temperature of each cloth as it heated up under the light were
Colored fire is a common pyrotechnic effect used in movies, fireworks and by fire performers all over the world. Generally the color of the flame may be red, orange, yellow, or white, and is controlled by blackbody radiation from soot and steam. When additional chemicals are added to the fire, the flame would appear a different color according to the other chemicals. Flame coloring is also a good way to show how chemicals change when heated and how they change the matter around them.
Glow sticks are made up of many different elements. These elements include sodium carbonate, luminol, ammonium carbonate, copper sulfate pentahydrate, distilled water, diphenyl oxalate and hydrogen peroxide. Temperature has a huge effect on glow sticks, cold or warm. It is said that the warmer the temperature the brighter the glow stick but the chemical reaction time isn’t long and the cooler the temperature the dimmer the light but the chemical reaction time lasts way longer. So how does a glow stick glow?
To continue the experiment further I can use a different source of light to test the intensity of light. For the food coloring experiment, I could use a different food color such as yellow or orange to test.
When it is summertime and I go on a run, my parents say, “Make sure you wear a light shirt!” Once, I asked why, and they said it was because the light colors don’t absorb as much heat, so I wouldn’t be as hot. The opposite was for cold weather. When I had to go outside for a while in the cold, I made sure to wear a black or dark top, because then it would absorb more heat and keep me warmer. I have always been curious about how this works, and if it works, for that matter (Parents can be wrong, you know). Also, the concept of energy simply intrigues me. This is why I decided to find out more about how colors on a shirt, or anywhere else, can affect temperature. When I started my research, the literature (or scientists) explained that a color will, in fact, affect the temperature of that object. This temperature is measured by using an infrared thermometer and a couple of large math equations. With this information, one can then calculate the rate of energy absorption of each color.
Why is blue light a problem, and not another color such as red? Blue light is at the edge of the visible light spectrum. Just beyond blue light lies ultraviolet, an invisible but highly energetic form of light. It is this high energy that damages the skin
The electromagnetic waves range from extremely short gamma rays, to long radio waves. Within that continuum is visible light which is the only light humans are able to perceive. As humans, we associate colour with the different wavelengths – blue being on the shorter side of the spectrum and yellow and red being on the longer side, while green sits in the middle. For humans to see anything, visible li...
Conduction, Convection, and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation. The first kind of heat transfer, conduction, is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly, therefore making the pan hot.
When choosing a colour for a room or house it is important to think about the mood and atmosphere you would like to achieve. Is it a dark room or flooded with natural light? In which direction is the room facing? How are the proportions? Do you live in a small apartment or a contemporary newly built house with open plan living areas? All this needs to be considered when choosing colours for a space.
The second process was chemical. For hundreds of years before photography was invented, people had been aware, for example, that some colours are bleached in the sun, but they had made little distinction between heat, air and light.
Be reflected off an object, travel through it, or be absorbed by the object. There are multiple properties of light that have been identified; they are Frequency, Wavelength Spectrum, Polarisation, Propagation direction and intensity. (Wikipedia, 2014) Light comes from multiple sources, the main one on earth is the sun, however there are other sources, such as lights/lamps and fire. Without light, we would not be able to see anything, as our optic nerve interprets light and other aspects as colour and allows us to see. Reflection is light radiation that is viewable by the eyes of humans. It is part of the reason why we can see so well. (Wikipedia, 2014) Another element of light is refraction. This is when a wave of light changes direction (bends) when it passes through different mediums, such as water, glass and others. (See diagram 1.1) Total internal reflection is another property that l...
Light is what lets you experience colour. The pigment of the retina in your eyes is sensitive to different lengths of light waves which allows you to see different colours. The wavelengths of light that humans can see are called the visible colour spectrum.
...the term color spectrum. Although the spectrum appears to be continuous with no discrete division between the colors in the spectrum he decided to divide it into seven colors which are as we know it red, orange, yellow, green, blue, indigo, and violet, also known as to some as (ROYGBIV). Newton showed that every color had a unique angle of refraction which can be calculated using a specific prism. Isaac Newton saw that all objects appear to be the same color when the beam of colored light that illuminates them, and the beam of colored light will stay the same color no matter how many times it is reflected or refracted. This led him to his conclusion that color is indeed a property of the light that reflects from objects and not a property of objects itself. Albert Einstein and Isaac Newton have both laid down the foundation for much of the science we see today.
yellow and blue could create a cool and calm mood from the blue and draw attention because of the yellow
Refraction of Light Aim: To find a relationship between the angles of incidence and the angles of refraction by obtaining a set of readings for the angles of incidence and refraction as a light ray passes from air into perspex. Introduction: Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's Law. (Refer to diagram below)
The rainbow inspired scientists to further explore the nature of color and light because the rainbow allowed drawing the conclusion that color is somehow connected to light. If we want to better understand color, we must take a closer look at light. And, if we want to better understand light, we must care about energy.
