sRGB
The default color space of the web: a dependable but limited range that almost every screen, browser, and image tool understands.

What it is
sRGB is the default color space of the web and the common ground for screens, browsers, cameras, and image files. It fixes exact red, green, and blue primaries, a D65 white point, and a transfer curve, so the same three RGB numbers have a shared meaning. CSS hex colors, rgb(), and hsl() all describe sRGB colors unless another space is named.
Reach for sRGB when compatibility matters more than the widest possible range: logos, screenshots, social images, email graphics, and fallback colors. HP and Microsoft proposed it in 1996, the IEC standardized it as IEC 61966-2-1, and its limited gamut became the safe box that web color lived inside for decades.
Gotcha: sRGB is a color space, while RGB is only a mixing model. Also, stored sRGB channel values are nonlinear, so averaging them directly makes blends too dark. Convert to linear-light sRGB before doing light math, then encode the result back to sRGB.

Prepare this palette for ordinary web delivery in sRGB. Convert every source color to IEC 61966-2-1 sRGB, flag any color that falls outside the gamut, and reduce its OKLCH chroma until it fits while preserving lightness and hue as closely as possible. Output a hex fallback and a CSS color(srgb r g b) value for each swatch. Export raster assets with an embedded sRGB ICC profile, and perform all gradient interpolation in linear-light sRGB before encoding the final channel values.
