After taking a closer look into first Petri dishes it was clear, that Slime mold actually didn't change the color - only agar around the body of slime mold was colorful. I started looking in the internet successful examples about coloring Slime mold and found this [https://slimoco.ning.com/forum/topics/painting-with-slime-molds-using-natural-pigment forum page]. People over there discessed a way of coloring Slime mold using iron oxide pigments, that are used in cosmetics, food packaging coloring and other diverse fields of applications. They supossed to be non-toxic, which means the slime mold might eat it.
