For this look I used these two colors, Revlon's Hot For Chocolate and Sally Hansen's Beige Blast.
I started by painting the pinky nail with the beige and the thumb with the dark brown.
For the ring finger shade, I mixed a very tiny amount of the chocolate color and a large amount of the beige.
This is how the color turned out.... but I would have liked it to be a little darker after I was done with them all.
After each color I mixed I made sure to wipe my brush off on the paper very well to prevent ruining the color.
For the next color I used equal amounts of both colors.
And more dark brown for the final color.
Here is how they turned out. I was pretty pleased with them and it makes me want to get started on mixing a lot more polishes.
