Yes, before you paint use some construction paper close to the color you would like. Stick them to the back of the glass with some tape and live with that for a day or so , then change it to the other color(s) you would be considering. Cheap and a great way to see what color you really like.
I did this and eliminated the black right away. I just did not like the look of it and prefer the blue.
Good Luck.....:cheer:
