Set Color effect outputs wrong RGB value (Solved)

The effect "Set Color" gives a different color than expected, mush lighter. The image editor outputs the correct RGB colors (matching external programs, i.e. photoshop).

But using Set Color RGB values must be lower 30/50% to get a similar color. Is there some hidden feature i´m not getting?

The "set color" values should be a percentage between 0 and 100, not 0 and 255. Could that be the problem? If you want red = 143 you'd set it to 143/255*100.

Thanks. That's the trick.
