Map Image Brightness to Gradient (vuo.image.color.map)

Alters an image’s colors by mapping the image’s brightness to a color gradient.

This node finds the perceptual brightness of each point in the image — that is, where the point falls in the range of black to white. It then finds the corresponding point in the gradient defined by the given colors — that is, where the point falls in the range of first color to last color — and creates a new image with those colors. Finally, it blends the original image with the new image.
