so in my instanced particles in geo node, the blue channel is the vertical Z coordinate,
say that it goes from -2 to +2,
what i want is to show a ramp from say two colors, from blue to red, blue in -2 and red in +2, and gradient from one to the other
I can assign blue channel of a secondary scriptTop I have (dedicated to the color) to r,g,b of colorValues in instance tab 2, but that will just make it all either black or white,
how do I assign a color ramp to the colors of particles to match the range of the vertical coordinate which comes from the blue channel of one of my scriptTops?
