This Sinful Colors orange will definitly cause your eyes to do a double take. I wouldn't consider this a neon orange however it is quite orange soda bright with lots of POP!!
I decided to swatch what a white base under this polish would look like. While it is nice either way I do prefer it with a white base. It is more obvious in person but with 3 coats of polish on my pinky finger you can still see my nail line.
What colors do you prefer to use a white base under?
