Hi I'm trying to color my crappy sketch.
I need a type of brush that makes a clear color so it won't cover the black lines
of my sketch. When I use the brush that I currently have, it covers up everything, How do I get thhis clear coloring?

Like in this photo, this is the type of brush I need, the brush that makes a clear pinkish color, please let me know if you know how I can get this type of tool.
