Step-by-step math

Every number below is computed from the input, nothing is looked up.

  1. 1. input

    oklch(0.86686 0.00000 0.000)
  2. 2. OKLCH → Oklab

    a = C·cos H = 0.00000
    b = C·sin H = 0.00000
  3. 3. Oklab → LMS′

    l′ = L + 0.3963·a + 0.2158·b = 0.866860
    m′ = L − 0.1056·a − 0.0639·b = 0.866860
    s′ = L − 0.0895·a − 1.2915·b = 0.866860
  4. 4. cube

    l = 0.866860³ = 0.651399
    m = 0.866860³ = 0.651399
    s = 0.866860³ = 0.651399
  5. 5. LMS → linear sRGB

    R = 4.0767·l − 3.3077·m + 0.2310·s = 0.651399
    G = −1.2684·l + 2.6098·m − 0.3413·s = 0.651399
    B = −0.0042·l − 0.7034·m + 1.7076·s = 0.651399
  6. 6. linear → sRGB, × 255

    R = 0.82745 × 255 = 211.00 → 211
    G = 0.82745 × 255 = 211.00 → 211
    B = 0.82745 × 255 = 211.00 → 211
  7. 7. RGB → HEX
