Today I'm wearing a sunflower-yellow nail polish - KIKO 355 Canary Yellow. I've never worn a colour like that plain on my nails before, only used it in connection to nailart. I must say, it looks extraordinary at first but I like it so much! Especially because it looks great on my tan skin. (On the photos my hand looks rather red but that's because the sunlight was soooo bright. ;))
I had to apply two coats of Canary Yellow to make it really opaque. Some people might want to add a third layer, but that's just your choice!
Note: The first three photos were taken in the sun, the last one in indirect sunlight.
