0x003B15

0x003B15 is a hexadecimal literal that, when interpreted as a color, encodes the RGB values red 0, green 59, and blue 21. In CSS notation, the same color is written as #003B15. The corresponding decimal RGB triplet is (0, 59, 21). This yields a dark green shade with low overall brightness.

In color space terms, the color has an approximate hue of 141 degrees, saturation near 100%, and lightness about 11.6% when represented in the HSL model. Its low lightness and high saturation give it a strong green character, suitable for deep, nature-inspired design palettes. The color’s luminance places it among the darker tones, making it useful for contrast against lighter backgrounds.

Applications and usage of this color often occur in digital design and UI theming. It can serve as a subdued accent or a background fill in dark-mode interfaces, as a badge color for important but non-urgent status indicators, or as part of a forest-green palette. When used against white or light backgrounds, the color provides a contrast ratio of about 4.8:1, which is generally acceptable for normal-text accessibility under WCAG guidelines.

Context and naming considerations vary. While 0x003B15 denotes a precise RGB value, it is not a widely standardized color name, and users typically refer to it by its hex notation (#003B15) or as RGB(0, 59, 21). The prefix 0x is common in programming to indicate a hexadecimal literal, and in color contexts it serves to denote a hex value rather than an address or identifier.
