been trying to find "muh-style" lately.

So basically there's 3 layers. It kinda works on general situations, But it seems not working on high contrast environment. Pic I posted is example of my obstacle.

I acknowledge there is various way to colorize certain things, but I really like to use this method. And the problem is, whether it's screen layer or multiply layer, It just doesn't look right.
Well, It does get better when I use wide range of color in screen/multiply layer. But as I understand, If light source is yellow, then every surface toward it has to be tinted yellow. So in theory, It has to be look right when i use screen/multiply layer per light source. But It is not. I really want to know why this happens
