Currently, NVDA only has color names for the 16 html3 web-safe colors. We should upgrade that to at least the CSS3 140 (x11) color names. Also we should improve the color matching algorithm to take hue into account more than it currently does, so that it won't so easily match to black/grey/white (#4970).

Increase list of known colors to include all CSS 3 colors. Also improve the closest color algorithm to use a weighted hsv (with hue 4 times more important) instead of rgb.

Fixes #4984.

Reported on nvda-translations: Aqua and Cyan both seem to have the same value (0, 255, 255).

where did you get names of collors? I think red and medium red are the same.
