The idea

Allow variables to be used when editing the tinting of an image, could be heavy on performance if used wrong but I think we're fine these days with the customizable caching durations and all that good stuff - possible fix would be limiting this sort of stuff to advanced mode.

Use case

I would only need to tint my elements to create accent colours rather than spending hours creating 30 different textures for every type of element I want my accent colour to apply to.
