Description czd 2009-05-31 09:27:00 UTC
* HSL (and HEX [3]) color palettes. Example: 100% Red = 1, 50% Red = 0.5
no rounding problem with the HEX model [3]. Example: 100% Red = 255, 50%
Red = "127.5" rounded "128".)
 * The HSV model is not symmetrical to lightness (white) and darkness
(black). HSL (or HLS) model (hue, saturation, lightness) [1]
 * CMYK color palettes

Example Color Palette XML File (like sK1 [4])
---------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<palette>
  <description type="CMYK" name="Red Palette" />
  <color c="0" m="1" y="1" k="0" name="Red" />
  <color c="0" m="1.5" y="1" k="0" name="Red 2" />
</palette>

Comment 1 Martin Nordholts 2009-05-31 09:40:00 UTC
Did someone tell you to file this enhancement request? Since I probably would know about it I'm closing this as INVALID just as bug #583908. Don't file this any more please.
Comment 2 czd 2009-05-31 10:10:39 UTC
Why invalid? The HSV model is not symmetrical. Point.
Comment 3 Martin Nordholts 2009-05-31 10:12:02 UTC
It is invalid because you didn't follow the process of filing enhancement request. Once this has been properly discussed on the gimp-developer mailing list we can consider reopening this (but we are likely going to ask you to write a new one with better content)
