1. do radio waves and gamma rays and such have specific colors associated with them depending on their wavelength, to things that do have the ability to detect them(in other words, not to the human eye), or is "color" only produced by the wavelengths of light that living things are able to detect? I'm guessing this may come down to deciding what the definition of color is...

3. a colour isnt wavelenght. colour is how a organism is percepting things. you can percept light but see no colours for exempel

No, surfaces vary in their refraction, reflection, absorption of EM waves, where this occurs at wavelengths between about 470 and 700 nm our eyes 'percieve' colour. color is not real, that is why you won't find a mathematical formula for it anywhere, associating it with wavelength.

5. when light from an object changes the medium will the colour change?

6. Er, no?

Chemboy, take a look at this website to learn a little about colour.

Here's one:

Believe it or not, squares A and B really are the same colour. The illusion that they aren't, is totally in your head. Most people who see this for the first time can't believe it. But I assure you, it's true.

7. thanks for the useful site
