I'll sometimes water down the acrylic. Just not blue. Blue is more amazing as watercolor. I just find it sometimes works better to go back over some edges with acrylics, specially white. Red, yellow, also. Can kind of pull out a bit more brightness with slightly watered down acrylic (just so it's really flowy, or you can use a medium since that makes it more translucent too)
I'm messy, never use masking fluid and an abuser of using white
I'm surprised titanium white isn't a cult by now. "Hated, repressed, shunned, he has risen from the abyss of artistic disdain and will taint the world of art one glorious day, yada yada yada..."
The world will fear me when I get back to oils. I have a lovely tube of zinc white. I just kind of like holding it. Soooo much heavier than my other tubes of oil lol
