Question

Outer glow CMYK vs RGB

I am creating this graphic in Illustrator and InDesign. It is using an outer glow with the same magenta color as the fill of the shape. Normal blend mode 100% opacity.

I would like to get a similar glow result in CMYK as I get in the RGB version. I do know there are significant differences in the RGB and CMYK color spaces.

Still I was hoping there might be some tricks to achieve a less white glow.

I already found this thread. But unfortunately the solution isn’t working since I don’t have a black background.

If you could change your background to 0/100/60/100 you will see the desired result.

The outer glow creates a gradient form the background color to your object's color.

Your object has no C and no K but full M and a lot of Y.

Your background has lots of C and K but only little M and Y.

What color is your background?  Cannot really make a recommendation without knowing that.  I would experiment with different Blend Modes to see what works better.  You say 100%, but against what color?

Yes sorry for leaving that out:

RGB: #e40045 on #303c49

CMYK: 0/100/60/0 on 63/32/14/76

I tried that already and it makes the color of the glow just a little bit brighter but doesn’t knock out the dark blue.


As you can see in the separation tables you will never get a good result.
