7FFF00

7FFF00 is a hexadecimal color value used in digital color representations. In the RGB color model it corresponds to red 127, green 255, and blue 0, yielding a bright lime-green color. In CSS and HTML, this hex value is the color defined for the named color chartreuse, which is #7FFF00 in the CSS Color Module.

The color sits in the yellow-green portion of the spectrum, with a hue near 90 degrees, and a saturation of 100% and lightness of about 50% in HSL terms. It is part of the sRGB color space and is widely supported across software, web browsers, and design tools.

In design usage, 7FFF00 is highly saturated and visually strong, making it effective for accents, alerts, and high-visibility elements. However, its brightness can strain legibility when paired with light backgrounds, so accessibility considerations such as sufficient contrast with adjacent text or icons are important. When used in palettes, it is commonly balanced with dark neutrals like black or deep gray, or complementary purples to create visual contrast.
