-		Given a set of colors, this node will interpolate them in order, meaning, that if you have color 1, color 2 and color3, the ramp will interpolate (generate the colors between two colors) from color 1 to color 2 and from color 2 to color 3. Initially the ramp will have 2 colors (black and white), one (black) at ramp lower offset offset 0 and the other (white) at the ramp higher offset 1.
