Block Tint Help

hey, im doing a biome in a dimension, i dont have any particular skills in MCreator and my works are private for now. I was doing a block stone-like for the ground of this biome that randomly changes colorization in the coordinate you place in, like the Optifine's CTM. I searched a bit on the MCreator options and i found the block tint, but in the helpbox doesnt say how to do it, i was wandering how to customize this "colormap" for the block, any help is welcome
