CMYK colors get recalculated in a document with color mode changed from RGB to CMYK, using Color Picker
According to the user, they often receive files created in RGB mode, and they have to convert them to CMYK, using File > Document Color Mode, make specific changes and push documents further. And while the document becomes CMYK, Ai keeps recalculating supplied values, as if these get double-converted via RGB space.
There are easy steps to reproduce this problem from scratch.
1. Create a new RGB document, using Web Document Profile
2. Go File > Document Color Mode > CMYK
3. Create a rectangle
4. Open Color and enter a CMYK color, like 15-30-45-15, tabbing through values. Press Enter while being in the last K field.
5. Open Color Picker again and check the values.
Expected — CMYK 15-30-45-15.
The one I get, using my Color Settings, is 21,15-32,8-47,81-7,71
If I enter these same values in Color panel — they get accepted fine.
Sometimes the Color Picker becomes sane and stops converting, but I haven’t figured out actions needed... perhaps something with the order of focusing fields?
My guess is that somehow Ai treats the HEX field as the last selected one (even though it’s not), adn uses the value in it as the final choice...
Please fix.
