Color Gradient doesn't work for texture particles
I’ve been trying to get anything color option to work when using a texture and it doesn’t seem to work. It defaults to the color of the texture and you are not able to change it to anything else unfortunately.
Colorising Textured Particles should be available soon. It is not supported yet.

This answer is a bit outdated, under Texture / Texture Colour use, you can set to use the Alpha or Lightness of the source texture and so to replace it with Color.
Is there any way to colorize a particle texture? I have some tree images (vector drawings with only 2 colors) and I want to vary the colors, but I don’t want them filled in with a solid color. If it doesn’t exist, something similar to AE’s built-in “Tint” or “Tritone” effect would be amazing. You’d just have two gradients (or 3 for Tritone)- one for tinting the whites and one for tinting the blacks. Then Stardust could choose a random color from each gradient per particle to colorize them.
