Green is considered one of the additive primary colors. The perception of green is evoked by light having a spectrum dominated by energy with a wavelength of roughly 520–570 nm. The complement of green is a purple, such as magenta; that is, a color corresponding to a mixture of red and blue light. On a traditional color wheel, based on subtractive color, the complementary color to green is considered to be red.
Bright green is bright shade of green. It is on the color wheel approximately one-third of the way between chartreuse and harlequin (closer to chartreuse than to harlequin). Bright green represents a visual stimulus of 556 nanometers on the visual spectrum as measured on the CIE chromaticity diagram.
