please help me out, i've started this project in B+W and want to add color on her skin. if i use yel red and a bit of blue trans to make the skin tones, is there gonna be any difference from using opaque?
You just need to be aware that with opaques after a few layers it will reach the optimum colour, and go no darker, With transparents the more layers you add, the deeper the colour gets, go to far, and you could go too intense.
