ICC Profile
ICC Profile (International Color Consortium Profile)
An ICC profile is a standardized data file that characterizes a color device (monitor, printer, scanner) or color space. Embedding ICC profiles in images ensures that colors are reproduced accurately across different devices.
ๆๆฏ็ป่
ICC profiles follow the ICC.1 specification and contain header information, tag tables, and color transformation data. Common embedded profiles are sRGB IEC61966-2.1 for web images and Adobe RGB (1998) for print workflows.

```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];
}
