Hi Everybody,
It has appeared to me for a very long time that the CMYK colors chosen from the CMYK color docker do not display correctly in either DRAW or Photopaint.I have no idea why this is happening.
Here are five hues (tints, whatever) for equal value for magenta and yellow. Those values have nothing to do with the eyedropper tool. They are the entries in the CMYK color docker. The hue starts out as red. Then almost immediately shifts to orange. Then to orange-yellow. That does not happen if you vary the transparency of the (0, 100, 100, 0) layer. In that case, the hue remains constant as the lightness varies.
I have simply ducked this problem by using RGB. The hue remains constant in RGB as the values are changed proportionatately
Just out of curiosity, has anyone else noticed this behavior. Could it possibly be "normal".

HI Phil
it is not your imagination it is the way cmyk works
As you know the cmyk color space is based on printing inks those inks are in fact transparent do you see anything transparent in your cmyk objects, no because they are displayed as though opaque on white the hue change is because 0 black is 100% white you are changing the colors m and y in relation to 100% white
this shows the difference between applying transparency and mixing percentages of colour both print the same but the display properties are different due to an alpha channel being used for transparency
The eyedropper sees both as the same value.
