Step 2: Working that paint to a lighter color, PURPLE!
I used the same sponge(it dried) but you can switch it out if you want.
So again, put a dime size splotch of paint on your palette and dab your sponge into the paint again.
This time dab the purple paint on top of the blue but don't paint over all of the blue.
Again, build up the paint and wait between each coat before adding more paint.
You want to gradually build the paint and give it a "gradation" effect.
