Corroded nails

So I was just playing around with colors and my fan paint brush and stumbled upon this look. I used four different colors and brushed them while they were still wet. I did one finger at a time. I think they look similar to a corroded penny but there is a little bit of blue in there.

The four colors used from bottom to top are China Glaze Shocking Pink, China Glaze Four Leaf Clover, Zoya Paz, and China Glaze Frostbite. The pink didn't show much but that's OK because I think they look cool.
