How can I change the Pos Value (marked red) of the two markers (also red) with a node (maybe a Math Node)? Is it possible?

I think you have 2 options the first and probably the easiest is to use this great node group by DanielFox
Perhaps you wanted to animate a color ramp, or wanted to vary a color ramp used for hair color based on texture, or whatever. You would need a color ramp node with color inputs. I don’t know if someone’s already done this, but I couldn’t find one. So I made one.
This one has four stops. It behaves like the default Cycles color ramp set to Linear. There is no support for alpha. If people find this useful I might make some with more stops and perhaps alpha support.
Happy ramping!

It gives you inputs for the colour ramp and can be very useful.
The second would be to use a driver but it would be more complicated as you need something to drive the value (maybe a custom property)

Hi DNorman,
Thank you for pointing out this nice solution (which appears to have been around for a very long time). DanielFox’s node group is quite handy and fun to play with. It’s quite clever too. Plus it seems to work with both Cycles and Eevee.
Cheers and stay safe!
