Cobalt is a chemical element (Co) with an atomic number of 27. As a free element, it's naturally a hard, lustrous silver metal.
The pigment cobalt blue was identified in 1802 by the French chemist Louis Jaques Thénard. While experimenting with cobalt, he discovered mixing cobalt oxide with aluminum oxide created a highly-stable rich blue pigment.
Cobalt blues are gorgeous, vibrant colors. On the nails, cobalt blue is a fantastic summer color. It’s reminiscent of deep, clear ocean waters and makes a stunning compliment to any look.
Below are swatches of four of the best cobalt blue nail polishes we’ve found so far, all in 2 coats.
essie push play
It’s the namesake of the 2023 push play summer collection and a creamy cobalt blue that’s very easy to apply.
China Glaze Frostbite
Frostbite is a cobalt blue pearl nail polish that is perfect for hot days. Wear it to feel chilly during any summer heatwave.
Nails.Inc Summers Street
From a limited edition Target-only summer neon collection, Summers Street is a medium coverage cobalt blue nail polish that will appear semi-sheer if you have nail tips. You can build this one for more coverage.
Morgan Taylor Anime-zing Color!
Anime-zing Color! was first released as a dark neon purple in the 2015 Hello Pretty! Summer Collection.
Our bottle is 4 years old and neons tend to fade over time, so today, this color is a rich creamy, cobalt blue with slight purple undertones.
This color is still in production.
If you get it new, it may be closer to the original dark purple neon in tone. However, depending on when it was manufactured and how it was stored, it may be more of the cobalt blue shown above.
