I'm pretty sure you can get away with putting the basic colors as names. Black, green, red, blue, etc.
If you want a quick summary of hex codes, I can give it to you. Basically you have #------. Each group of two represents the amount 3 different colors, red, blue, and green. A number of zero means the lowest amount of color while the letter F is the highest. Therefore, #FFFFFF is white, since it's the highest of all three. #000000 is black for the opposite reason. #FF000, #00FF00, and #0000FF are green blue and red, except I'm not sure which is which. :I
