I heard you can put pigment in Fix+. Is that true? If you do this, is it nice? Also what color pigment do you put in? I am planning to get Fix+ and a pigment soon.
You really only need the slightest amount. At the most, 1/8th of a teaspoon. Probably less, depending on your tastes. Start with a little and add a little more if you feel it needs it.
To my tastes, I find that Vanilla pigment gives the best result.
