Well, it's all a process, isn't it.
I mixed up a bunch of "white" (actually it had a lot of ochre and gloss medium and some pthalo blue). I didn't like the reddish brown color I had put on the last time. There was too much of that color on the upper left corner and it started to look very much like a Christmas painting-- lots of green and red. So I decided I would basically cover up most of that reddish brown color.

The glossiness and translucency of the white came out pretty well. So it wasn't a completely failed experiment. (Plus, I erased that distracting image which I kept seeing in the center of the painting.)
In fact, I liked it quite a lot, so I rather impulsively painted on the "finished" blue and orange painting which is hanging above the mantel in our living room!
I actually think it is improved. (the one on the right)
