Tip on masking tape when painting
Basically when painting in two colours with masking tape, after you have done the masking over the "Base" colour, paint the base colour again on the non masked areas where you want the accent colour, let it dry an apply the accent colour. In this way the base colour will bleed under the tape, and seal and prevent bleeding from the accent colour.
The base is the color that's under the tape. Doing it this way lets that color bleed under the tape, but you won't see it because that's what color that part of the wall already is.
