#2FEC00

sRGB · 47 / 236 / 0

#2FEC00 belongs to the green family. Its hex code tells a screen to mix 47 red, 236 green and 0 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 108.1° lands in the green region. Its 100.0% saturation makes it strong in color at this lightness. HSL lightness is 46.3% on a scale from black (0%) to white (100%). Of black and white lettering, black has the clearer light-to-dark separation on this background (13.12:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #2FEC00 in light and dark. The ratio compares relative luminance, a measure of light weighted for human vision. Identical colors give 1:1 and black against white gives 21:1. A ratio of 2.99:1 falls just below the 3:1 AA minimum for large text. Body text needs at least 4.5:1 because its finer strokes are harder to distinguish.

Black text · 13.12:1

Normal text: AAA
Large text: AAA

White text · 1.60:1

Normal text: Fail
Large text: Fail

AA and AAA are WCAG accessibility levels. AAA sets a higher bar: 7:1 for normal text and 4.5:1 for large text. Large text begins at 18 pt regular or 14 pt bold. Ratings use the unrounded ratio. WCAG text contrast guidance

Palettes & scales

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#BD00EC sits half a turn (180°) from #2FEC00 on the HSL wheel. Keeping saturation and lightness steady while crossing to the opposite hue gives you a contrasting accent. Check text contrast separately before using the pair for lettering.

#2FEC00 #BD00EC

Analogous

#A5EC00 and #00EC47 sit 30° to either side of #2FEC00. The three hues are neighbors on the wheel, so you can change the color of a border or highlight while keeping it close to the original.

#A5EC00 #2FEC00 #00EC47

Triadic

#2FEC00, #002FEC and #EC002F are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.

Split complementary

Start at #2FEC00 and look across the wheel. #4700EC and #EC00A5 sit 30° to either side of its exact opposite, giving you two different accent choices.

Square

Starting with #2FEC00, each quarter turn (90°) takes you to the next hue: #00A5EC, #BD00EC, then #EC4700. Across the square, #2FEC00 pairs with #BD00EC, and #00A5EC with #EC4700.

Tetradic

#2FEC00 and #BD00EC are opposites, as are #00ECBD and #EC002F. Together they form a rectangle on the wheel, with alternating gaps of 60° and 120°.
