hi, there are two commands in the Color palette menu: inverse and complementary, but both give inverse... Do I do something wrong
or is it a bug? thanks

depending on the original color -
-say a cyan - they "look the same"but choose a pink and the invert and complementary are totally different.
Look under the "Help" in Illy app for explaination

I read the manual before asking here... but I don't get it anyway. I thought that complementary color is a color which is a direct opposite to any other color on a color circle (used e.g. at http://kuler.adobe.com). But results are completely different between Kuler and Illustrator. Maybe Illustrator use different "color model (not a circle)" or something else?
But thank you anyway, at least now I know what I did wrong before..

could it have something to do with cmyk vs rgb?
- jirkap0
I don't know if you're asking (probably not), or giving me a guide=if so, why it does not work the same way as Kuler does in RGB?
- aliceblue0
(From painting classes) two complementary colors when mixed together equal a neutral grey.
they are also found opposite on the color star by Itten.

example:
Illustrator complementary
for CMYK 0,0,100,0 is 88,77,0,0.
Kuler returns 55,100,0,0 (in CMYK mode)Ill. complementary for RGB 255,255,0 is 0,0,255.
Kuler returns 115,0,255.?

I'm not that familiar with Kuler - but seems you are not alone
- jirkap0
yeah, I've just read this, but that's not my problem anyway. I get the same colors in e.g. Illustrator as in Kuler. This guy doesn't... I do not want to use Kuler really, I want to use the lllustrator built-in commands, but I just don't get why it works differently
- aliceblue0
yeah, I know - things like that drive me crazy.
so, as you said - don't use Kuler
- save your sanity :)
- jirkap0
:) I'm gonna ask this to the Adobe Forums... thanks for help!
- aliceblue0
post if you find something!
- jirkap0
I will.

Teri Pettit - 4:07pm Mar 23, 07 PST (#1 of 1) Edited: 23-Mar-2007 at 04:08pmThe Complement command in the Color palette just converts to HSB, adds or subtracts 180 from the H value, and then converts back to the document's color mode. The trouble is that the HSB scale used in the color sliders does not correspond to most artist's intuition of what a color wheel looks like. A very large fraction of the wheel is devoted to greens, for example, and red is opposite cyan, which artists don't usually think of as the complement of red.
Kuler also uses an HSB color wheel, but the hues have been scaled so that the colors opposite each other are more like those used in artist's color wheels, where red is opposite from green, blue is opposite from orange, and yellow is opposite from violet. Many of the colors that are opposite each other on this scaled wheel will therefore have hue numbers in the HSB scale will that are not exactly 180 degrees apart.
This scaled wheel was copied by Kuler from Illustrator, where it has been used ever since AI 8 in the Brush options Hue Shift colorization method. The hue shift colorization method moves each color in the brush art by the same angular distance that exists between the brush's "key color" and the current assigned stroke color, and when it is moving colors by those angular distances, it is moving them around the scaled artistic hue wheel, not around the "raw" HSB values.
It will be used by more stuff in CS3, but you'll have to wait to see what.
