What is radiation and what does it have to do with color?

I am currently researching "Which color fabric makes ice melt the fastest" for my science fair. What is radiation and what does it have to do with my topic?What is radiation and what does it have to do with color?
(PhD physicist responds) radiation comes in two forms: moving charged particles and electromagnetic waves. Since you are talking about color we'll ignore colored quarks and talk about EM radiation. Light is one form of EM radiation. (including radio waves, Xrays, gamma rays, etc.) The colors of light are just light at different frequencies., just like tuning a radio. Red light has the lowest frequency, then orange, yellow, green blue and violet has the highest. since the energy of a photon is the mighest when it has the highest frequency, violet would be the answer if only one color could be used. However, if you can trap all light by the cloth, you want a color of cloth that stops all light colors, not just one color. White cloth reflects all colors, and black cloth absorbs all colors. Your answer would be black.What is radiation and what does it have to do with color?
Electromagnetic radiation, the larger family of wave-like phenomena to which visible light belongs (also known as radiant energy), is the primary vehicle transporting energy through the vast reaches of the universe. This interactive tutorial explores the classical representation of an electromagnetic wave as a sine function, and enables the visitor to vary amplitude and wavelength to demonstrate how this function appears in three dimensions.The tutorial initializes with a sine function simulating electromagnetic wave propagation traversing from left to right across the window. The oscillating electric field vectors of the virtual electromagnetic wave are represented by blue lines, while the magnetic field vectors are depicted in red. In order to operate the tutorial, use the mouse cursor to drag the wave back and forth in the window to observe how it appears from different angles. The Filled slider can be employed to vary the density of vector lines appearing within the sine function, and the Amplitude slider increases or decreases vector amplitude. Placing a check mark in the Show Wave Color check box changes to the wave simulate the color matching the current Wavelength slider value. This slider can be utilized to alter the wavelength of the virtual wave between a range of 300 nanometers (ultraviolet) to 800 nanometers (infrared). As the Wavelength slider is translated, the color corresponding to the current wavelength is acquired by the virtual electromagnetic wave (provided the Show Wave Color check box is active), and the name (red, yellow, green, etc.) also appears above the slider bar.
