You could 'reverse' fill the tape (if you didn't do that), like first mask it, paint over the tape with white, let it dry, and then paint with the color – the masking tape is then filled with the white color, and can't fill so much with the other color underneath. We have tried this hack once with white and a greenish color, and it was a little bit better for sure.
