I have used both Rit powder based and pre-made liquid based.
I also have used the food coloring liquid dye most grocery stores have.
Use dye and cup or two of water. Some people say adding vinegar helps.
My best results came from gently heating the dye. I put the dye jars in
a pot with water and heated the pot on the stove until the water in the pot
was hot but not boiling. Leave the model in the dye longer to darken.
Only works on Nylon for me.
If you add a little acetone you can "dye" ABS. Heat not needed.
I use the European stuff, Dylon. The powder works best, heated up just below boiling. Thin printed parts just need dipping, count to ten.... Just check by rinsing and see how it looks.
The sls printed nylon, which is thicker, needs from 10 minutes to 30 minutes, depending on the color.
