I experience small variations in the RGB values depending on the different programs I used to convert the color values in CMYK to RGB. So my question is if there is a preferred program to use InDesign, Illustrator or Photoshop?
I have synchronized the color profile of all programs via Bridge to European general purpose 3. (sRGB + Fogra 39)
My challenge, however, is that if I create the same CMYK color in one of the three programs and for example define the color Cyan (100, 0, 0, 0) and subsequently use Illustrator's color window to switch to RGB values (0-159-227), then it gives a different result than if I use Swatches in InDesign to convert with (0-157-224).
If I then subsequently compare with Pantone's RGB values for Cyan, it says something completely different (0-163-224).
This applies to virtually any color in the customer's color palette.
Do any of you have any good advice regarding which program to use for conversion to keep the best consistency in colors? The purse is to determine values for my clients brand guide (CMYK values are given - they need RGB numbers).
