Color Terms Commonly Used

On the bus home yesterday, I did this irritating peeking over my shoulder thing coz the gal sitting next to me was holding on to a piece of paper, who's information got me interested. The title says "Color Terms Commonly Used". First thought that came to my mind, she is supposed to use her color pencils or highlighters to shade off the commonly used terms. Erm...no... The answer was displayed in the rest of the paper, in the manner of 5 main words and corresponding paragraphs of explaination. It took me a while to finally get it. Hue, Intensity, Shade, Tint and Value. She must have been an Art student.
