Purple

I'm browsing through Wikipedia, learning all about ... well, lots of things ... and I notice that in one article the word "purple" is linked. So I followed the link. Here's what I discovered:

Hex triplet #660099
RGB (r, g, b) (102, 0, 153)
CMYK (c, m, y, k) N (50, 153, 0, 102)
HSV (h, s, v) (280°, 100%, 60%)

Where:

• RBG - an "additive light model" formulation for color
• CMYK - a "subtractive model" based on solid pigmentation
• HSV - is some kind of fancy something or other I didn't fully understand

There you go. Who would have thought that so simple a word would have so much background behind it?
