I am trying to mimic the nice "tritone" color effect which is included in Adobe After effects. It colorises an image using a 3 color gradient.

To colorize and image with two colors we simply can use the mix object.

Here is a patch, which is generating the 3 color gradient.

I think what I need is using the gradient as a lookup table not as an input.

you should use the "jit.gradient.ui" object to build a 1 dimensional gradient. 

Then in the jit.gl.pix you use the luminance of the input image as the index for the color in the gradient

This patch is much more elegant than mine :)
