As I said a few days ago, I've been playing with some shimmery colors lately and test driving how I can use them most effectively. I did this chart to see what would happen layering assorted Golden Interference colors over some of the Golden Iridescents. I also made one row black, and left one the white of the paper, to see the color shift from light to dark (which is way more dramatic than I thought it would be!) There's some glare on the page, but I used this photo because it's when the light hits that you can see some additional effects. As you can see, the interference colors on black are really beautiful! Now I'll have to explore using these with other dark colors too.
