What if you want to push those shadows into a black -> red territory with a touch of orange in the extreme areas? Like there is fire or something below him. Would it be possible to underpaint with red lile you did? Just keep spraying. Or would it be better to start with a red brown before pure red? 🤔
I would probably go red brown before hitting pure red then to orange when it comes to a fire. The more variation in color and with the gradient is generally preferable. And when you are dealing with OSL then a little black mixture just as the colors transition from one to the other is helpful in selling the effect. So if we had a green and we wanted that red from underneath then we want some transition between those two colors and a blackish mixture would do the trick.
