Rigostep COLOR for OIL is a color pigment that can be mixed with Royl Bio Oil and Royl Oil 2K. These pigments ensure that a clear primer or oil gets a certain colour. Every colour pigment creates it's own unique appearance. If you want the color to become less intensive, you can pour less in the oil or primer. For a more intense and fuller colour, you can add up to 2 colour pigments to 1 litre of primer or oil. In most cases, 1 color pigment is sufficient. We recommend you carry out a test beforehand, in order to determine the colour.
