Title: Tar Colour - Can the colour change by adding chemicals? Post by: prashantakerkar on May 15, 2019 https://en.wikipedia.org/wiki/Tar Can the tar dark brown or black change by adding chemicals to have Red, Green, Blue, Yellow etc colours? If yes, How? What will be the chemical reactions for the same if possible? If no, Why? Thanks & Regards, Prashant S Akerkar Attached Tar image.

Mixing in a coloring agent with a solvent could dilute the tar, potentially changing its color, but the colorant to tar ratio would have to be substantial!
