You don't need these specific polishes, but these are ones that I want to reach for during Spring. I seem to have gone for all pastel polishes this year.
Rose Hip is a very light pink cream shade which is pink enough not to just look white.
Huckleberry is a light blue shade, lighter than a Tiffany blue and again blue enough to to look white.
A typical polish for St. Patrick's Day would be something green, I recently got this shade Peacock from Aj Nails Collection which is a very neon green.
