I am just curious. Is the way contrast colors work over white prime similar to what i have chosen to be my main painting technique? I prime white. Take any color I like. Mix it 2 or 3:1with lahmian medium. So i have highlights through the white prime and the very thin color and simultaeniously recesses darkened. If it has to be darker i take another run with either a fitting shade color or a dark base color mixed again with medium
i actually hardly ever do real manual highlighting except for drybrushing as my hand is not calm enough and it takes too long.
