Acrylic
I am trying to do a dark night sky.
I thought it would be richer if I use a blueish tone, like Payne Gray (just to find out that it was simply carbon black (PB 29) with ultramarine (PBk 7).
I am running into 2 problems with the Payne Gray:
1) It poorly covers the canvas, although the black part is labelled as opaque. Already 2 coats and still not good.
2) I added 'open acrylic medium - matte', instead of the standard medium... to have more time to paint the background. The paint now has a guey texture, which I dislike. I mixed well, add few drop of water, no change. Could it be a bad bottle of medium? (doesn't smell bad!)
I also have some Mars Black (PBk 11), but no Carbon Black.
Thanks
