Sure would like to come up with something that is worthy to be posted! Stu, you suggested I don't throw away any of my paintings but sometimes I don't want to be reminded of failure!!!

Comment by Stuart J. Gourlay on September 15, 2013 at 2:48: Yeah Jim, mine was all dry. But I used all transparent colors. If you use cadmium yellow, an opaque pigment, the blue will not show through as much. Also, I could kill the green with some red. But, all in all, this was supposed to be a learning experience; and that part worked real well because I learned what not to do if I don't like greenish skies. Stu

Comment by Jim Haycock on September 15, 2013 at 1:36: My first attempt did the same thing -- turned green. Mine looked like a giant cow pasture in the sky. But, I found that scumbling a really thinned mix of lemon yellow and a bit of titanium white lightened the blue without turning the whole thing green. But the blue had to be very dry.

Comment by Stuart J. Gourlay on September 14, 2013 at 14:58: Linda, that's why I cheated and put some white back. Basically, the areas where yellow and orange are going to be glazed need to be a warm gray. My land is a nice warm gray and there is no greenish cast there. My lightest grays would have to have little black or blue in them to work well, because either black or blue glazed with transparent yellow will have a greenish cast. If these were just warm white rather than a gray it would work. Actually most of the dutch masters glazed their darks and used opaque paints for their lights. Rembrandt would glaze his light passages as well to make them glow. The IVenetian masters introduced this use of opaque paint rather than glazing and most of the Dutch masters eventually embraced it as well. Stu

Comment by Linda L. Kano on September 14, 2013 at 14:36: So would it be possible to glaze over the greenish cast to obtain the color you want? I don't know much about glazing.

Comment by Stuart J. Gourlay on September 14, 2013 at 12:27: Thank you all. I am not very happy with this and I even cheated and put some lighter opaque color back in. What I really don't like is the greenish cast where yellow and orange were used to glaze over a mid-value gray. Maybe that's why sepia, burnt sienna and burnt umber are used for grisailles sometimes? Silvana, it was completely dry because I used alkyd medium and did not paint that thick. If it is not completely dry, the solvent in your glazing medium solubilizes the underlayer and you make MUD! Mud is never appropriate in skies. Stu

Comment by Silvana M Albano on September 14, 2013 at 11:44: Nice Stu! Was it completely dry?

I've got this question...When a painting is dry to the touch, ut not completely dry, does anything unwanted happen if you glaze it?
