Color Space
Color Space (Color Model)
A color space is a specific organization of colors that defines the gamut (range) of representable colors. sRGB is the web standard, Adobe RGB covers more greens and cyans for print, and Display P3 serves modern wide-gamut displays.
Technical Detail
Color spaces are defined by primary chromaticities, a white point, and a transfer function (gamma). sRGB uses D65 illuminant with BT.709 primaries and a ~2.2 gamma curve.
Example
```javascript
// Convert RGB to HSL
function rgbToHsl(r, g, b) {
r /= 255; g /= 255; b /= 255;
const max = Math.max(r, g, b), min = Math.min(r, g, b);
const l = (max + min) / 2;
let h = 0, s = 0;
if (max !== min) {
const d = max - min;
s = l > 0.5 ? d/(2-max-min) : d/(max+min);
}
return [h, s, l];
}
```
