The index and ring finger were inspired by this fabric also found here
But I changed the background colour to blue.
I used Barry M in Blueberry Ice cream for the background and Mint Green for the light foliage
For the pinks I used the Nails Inc heathered grey and plum from the Diet Coke Promotion in Boots.
I also used a little acrylic paint for the dark green, Sinful Colors Strong Nails as a base and Seche Vite as top coat.
The most accurate photo colour wise is the last one.
