Neon Green

#2CFF05

What color is Neon Green?

Neon green is a blazing, electric green with an intense yellow-green brightness, hex #2CFF05, similar to the glow of a firefly on a dark night. It appears almost backlit, with a sharpness that makes it stand out against most other colors.

What is the meaning of the color Neon Green?

Neon green is named after neon lighting technology, though the color itself is produced by argon and mercury gases rather than neon, which glows orange-red. Fluorescent pigments capable of producing this shade were developed in the 1930s by brothers Bob and Joe Switzer, whose work led to the Day-Glo Color Corp, founded in 1946. Safety and visibility standards adopted the color for high-visibility workwear, and the European standard EN ISO 20471, governing high-visibility clothing, specifies yellow-green fluorescent fabric that matches this range. Day-Glo remains the most recognized brand name associated with neon green as a commercial color category.
