How to randomize toon shader colors

Question

I'm trying to do some beads for my model but I have a problem with the colors. I want to add lot of beads with geometry nodes and for that, randomize their color, but I don't know how to randomize the color when using a toon shader.

As you can see on the picture above, I tried a mix rgb node with the random and toon shader linked, but it only gives different tones of red. Is there a way to randomize the color ramp colors while keeping the same "configuration" so I don't lose the toon shader effect?

Also tried by randomizing the color ramp as a comment said, but if I add more colors, they will combine on the beads.

I'm not sure about the way you use the Random output, maybe plug it into a ColorRamp? — moonboots, Oct 11 '22 at 17:06
Use a Hue/Saturation node - connect your color to the color input, and the random to the Hue input. — Christopher Bennett, Oct 11 '22 at 17:27

One way would be to let Shader to RGB do the tone, and your GN attribute do the colour:

How do I add colors with geometry nodes? I tried by myself before asking, but I couldn't do it. – Kai Oct 15 '22 at 03:45
Hi, @Kai! See the answers to this question which show you how, both in current and alpha versions of Blender. – Robin Betts Oct 15 '22 at 05:42
