Can you change the color of mastic?

I'm talking about the white adhesive stuff that comes in a big pink bucket with a black lid.  Laticrete premium mastic adhesive.  It is a really great adhesive but I want it to be some other color than extremely bright white. 

I wonder if oil paint or acrylic paint or something could be added to it to change it's color.

Thank you for any thoughts

You could experiment with food colouring BUT I emphasise EXPERIMENT with small amounts
Laticrete mastic is water-based, so if you want to try and change the color, you should stick with other water based tints (acrylic or latex (definitely no oil) paints). Just keep in mind that the more "tint" you add, the less the adhesive may work. Ideally, if you can get some pure, powder tints you may have more luck as you'll require a lot less in order to change the mastic color. Look for the dyes from companies that tint thinset and grout.
