Color is the way light reflects off of a certain object. Certain colors can retain heat better, like black since it absorbs light. White reflects light, and is therefore cooler. This is also useful on a hot day, because black clothing can get stuffy and hot.

What is the difference between reflection and absorption?
Reflection is when a wave of light bounces away from the material, depending on the material it may maintain its strength. However absorbtion is when the beam of light hits a material and does not bounce back. To explain why light does not bounce back (becomes absorbed) you will need to know about the colour spectrum. A wave of white light contains, Red, Orange, Yellow, Green, Blue, Indigo and Violet. Certain coloured materials will absorb and reflect certain colours of the colour spectum. So say we aim our wave of light at a black filter. Black will absorb every colour in the colour spectum, thus not allowing for any reflection.
What happens when you shine a light ray into a light prisim?
When the light ray strikes the surface of the prism, both when it enters and when it leaves, it bends owing to the different in the speeds of light in air and the material of which the prism is made. The amount of bending depends in part on the frequency of the light which is related to the colour of the light, hence the appearance of a colour spectrum which can be seen from a triangular prism.
