I see these distinct colours:<br /> red 0,<br /> red-orange 30 (+30),<br /> orange 45 (+15),<br /> yellow 60 (+15),<br /> yellow-green 75 (+15),<br /> green 120 (+45),<br /> blue-green 160 (+40),<br /> cyan/sky-blue 180 (+20),<br /> blue 210 (+30),<br /> indigo 240 (+30),<br /> purple/violet 270 (+30), and<br /> pink/magenta 315 (+45),<br /> red 360 (+45)<br /><br />The average person have colour sensors for orange-yellow+violet, green-yellow, blue and overloaded green-cyan (rod).<br /><br />Since grey is 59% green, 30% red, and only 11% blue, implies the eye is *less* sensitive to green, but over a few seconds an AGC process takes over and adjust the sensitivity to each colour.<br /><br />On the computer monitor 255, 255, 255 is white, so it is already adjusted. <br /><br />See http://en.wikipedia.org/wiki/File:Cone-response.svgAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-17722541.post-71076004734644047212009-04-22T10:40:00.000+02:002009-04-22T10:40:00.000+02:00For me, even in the "machine" model there is too m...For me, even in the "machine" model there is too much green already. I can't really distinguish between the middle quarter of the green region there. Having a wider range of yellows would be nice though. I think that, in general, having an even distribution of the spectrum is the way to go.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-17722541.post-13948469668392163622009-04-22T01:29:00.000+02:002009-04-22T01:29:00.000+02:00Something I think might affect peoples impression ...Something I think might affect peoples impression of the a wheel is the rotation of the colors. On the 'human version' green is at the top, so when peoples eyes natually gravitate there at first you recognize a giant span of green. Maybe placing the green near the bottom might make it slightly more appealing?Gregory Hayneshttps://www.blogger.com/profile/03545073574400319988noreply@blogger.comtag:blogger.com,1999:blog-17722541.post-86613123599077804352009-04-22T00:59:00.000+02:002009-04-22T00:59:00.000+02:00PS: This problem has already been solved (better!)...PS: This problem has already been solved (better!) by the LAB colourspaces.Timhttps://www.blogger.com/profile/14408908510164973992noreply@blogger.comtag:blogger.com,1999:blog-17722541.post-7068997452711774892009-04-22T00:57:00.000+02:002009-04-22T00:57:00.000+02:00I concur.

In "human" model there is still red on 0 and something similar to yellow (with a bit of green) on 0.167, but on both 0.333 and 0.5 there are some greeny colors I can hardly distinguish. Differences in "machine" model are much bigger.<br /><br />Anyway, using subtractive model isn't bad idea. I always preferred to treat orange as more "primary" than cyan. But it's only subjective opinion.Pitazborashttps://www.blogger.com/profile/03450936812007380709noreply@blogger.comtag:blogger.com,1999:blog-17722541.post-80093080467587580702009-04-21T22:18:00.000+02:002009-04-21T22:18:00.000+02:00This comment has been removed by the author.Pitazborashttps://www.blogger.com/profile/03450936812007380709noreply@blogger.comtag:blogger.com,1999:blog-17722541.post-26974844498448347482009-04-21T22:09:00.000+02:002009-04-21T22:09:00.000+02:00Humans may be more sensitive to green, but that do...Humans may be more sensitive to green, but that doesn't mean we're any better at distinguishing different hues of green than hues of other colours. In fact, probably the opposite - our sensitivity to green may be what makes blue so distinct from cyan and red from yellow, while purple seems to fade evenly into both blue and red.<br /><br />Think about the differences between hues 90 degrees apart (or slightly less) on each wheel. On the "machine" wheel, there is a stark contrast between any two hues 90 degrees apart. On the human wheel, the top hue (one end of green) and the right hue (the other end of green) are very similar. At least, that is how it seems to me.Anonymousnoreply@blogger.com
