Color adjustment bug in PHOTO-PAINT X6

 Using X6 trial, I found that adjustment of selected colors (Adjust/Selective Color) in PHOTO-PAINT works very strangely. Mainly it applies to images in CMYK color mode.

For example, I have picture that contains Red, Yellow, Green, Cyan, Blue and Magenta color samples in CMYK mode.


 

1. Moving sliders in Reds spectrum affects on Blue sample, but not on Red.



2. Moving sliders in Yellows spectrum affects on Cyan sample, but not on Yellow


 

... And the same problems with Cyans and Blues .

5. Greens spectrum works correctly.


 

6. In Magentas spectrum, sliders really affect on Magenta sample, but they are working in inverse mode – moving Magenta slider toward ‘+’ direction removes magenta from sample while moving Cyan slider toward ‘-‘ adds cyan to it (if I do it in Absolute mode), etc.

 

For RGB colors, adjustment works almost correctly. Excluding Magentas. Here are the same problems as in CMYK.

 

All these problems are present in DRAW as well as in PHOTO-PAINT.

I tried to do the same in X5, and found out that there this function also does not work properly. In X3 this part of color correction have no these errors.

Finally I’m wondering – Is this the known issue? It seems very strange that so far no one paid attention to it.
