This colour combination will be featuring on the blog quite a bit in the coming weeks. Rainbow nails are just my thing lately. I think they boast your mood and just brighten up a crappy day (or make a good day even better). The only thing I would change is the base colour due to the formula. This is China Glaze Flip Flop fantasy. I love the colour, it's insanely bright, but it needs 4 coats at least to cover any bald spots. I have heard rumours that China Glaze re-released this with a better formula but I have no idea whether this is true or not.
The colours I dotted on my tips are: OPI I just can't copeacabana (yellow), Zoya Paz (orange) Catrice Run Forest Run (green), Sinful Colors Sugar rush (blue) and Nails Inc St James (red)
I topped it off with Sally Hansen Miracle Gel topcoat. I have done another mani very similar to this but with 2-3 different polishes. I love this design, it's so striking with the bright, neon colours. I think keeping the dotticure just at the tips makes the individual colours stand out nicely even against such a bright base.
