"It's not blue, it's cerulean"...bright, rich blue as the name implies.

The fine print:

Safe, clean natural nail color that’s not tested on animals and does not use animal-derived ingredients which means our nail color is vegan-friendly. A 10-free formula that’s free of toluene, formaldehyde, camphor, and other nastiness that just doesn’t need to be near those nails of yours.
