Input Color

Color Spaces Explained

• RGB / HEX: Additive light model. The primary format for screens and web.
• HSL / HSV / HWB: Cylindrical models that describe hue, saturation, and a luminance-like axis. More intuitive for designers.
• CMYK: Subtractive ink model used in print.
• CIE XYZ: Device-independent reference space defined by the CIE in 1931. All other perceptual spaces derive from it.
• CIE L*a*b* (LAB): Perceptually uniform space. Equal numeric distances correspond to equal perceived color differences.
• LCH: Cylindrical form of LAB; L = lightness, C = chroma (colorfulness), H = hue angle.
• Oklab / Oklch: Modern perceptual spaces (Björn Ottosson, 2020) with improved hue uniformity over LAB.
• LUV / LCHuv: Alternative CIE perceptual space, cylindrical variant.
• Hunter LAB: Earlier predecessor to CIE LAB, still used in some industries.
• YUV / YIQ / YCbCr / YPbPr: Luma/chroma decompositions used in broadcast and video encoding.
• Linear sRGB: sRGB with gamma removed; used for physically correct blending.

Conversion Pipeline

Every input is first normalized to linear sRGB triplet [0,1], then transformed outward to each target space:

1. Input (any format) → sRGB [0,1]
2. sRGB → Linear sRGB (gamma expand)
3. Linear sRGB → XYZ D65
4. XYZ D65 → LAB, LUV, Oklab, Hunter LAB, etc.
5. Cylindrical projections (LCH, Oklch, LCHuv) computed from their parent spaces
6. Video spaces (YUV, YCbCr, YIQ) computed directly from sRGB

All conversions use the D65 standard illuminant (daylight, 6504 K) and the IEC 61966-2-1 sRGB gamma curve.
