I may not be posting a lot tonight, but here is a great article / tutorial on Color which I think may prove useful to a lot of people.
I will definitely try to address this topic soon ~ but in the meantime, take the time to read through this article if Color ~ it’s really good, clear, and thorough:

[i]From the article:
[/i] Chroma: How pure a hue is in relation to gray
Saturation: The degree of purity of a hue.
Intensity: The brightness or dullness of a hue. One may lower the intensity by adding white or black.
Luminance / Value: A measure of the amount of light reflected from a hue. Those hues with a high content of white have a higher luminance or value.

Shade and tint are terms that refer to a variation of a hue.
Shade: A hue produced by the addition of black.
[b]Tint:[/b] A hue produced by the addition of white.
