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.
