Replace Grayscale Map with Linear Color

Maybe someone here can help. I have a model with a greyscale texture map. I also have a linear color map (gradient).

In blueprint I want to replace the greyscale value with the gradient color so that the highlights and shadows will pull from the corresponding value on the gradient.

Help appreciated.

I’ve found that Plugging two vector constants into a lerp with the greyscale as the alpha mask will sort of get me what I want but I’d like to have more control of how the colors change so that I can choose where and how fast it graduates or potentially have more than two colors.

Seems like a gradient would be a universally useful for this but I am unaware of a lerp equivalent that functions that way.
