I understand ok thank you
By the way, tonight I tried yellow ochre underlayer aproach and tried to paint blue color sea over top of it. It did not work for me. I wiped off all the canvas. It is a very small canvas.
Well I understood that for me sea is best painted by using wet on wet method. I am unable to paint sea in layers.
Tomorrow I will repaint a sea using wet on wet painting method.
But for the portrait painting, layered methods like the flemish technique works best for me.
And this maimeri artist grade zinc white is so powerful IMO. Even stronger than the student grade titanium white. But one problem it has is, there are particules in it. How ever I can easly mix them in to the paint with a palette knife. What are they? Particules of pigment?
