OKLCH to HEX: #1D1D16

Result

Values are shown at full precision, so converting back gives exactly #1d1d16. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. 1. input

   oklch(0.22823 0.01302 107.388)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.00389
   b = C·sin H = 0.01243

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.229369
   m′ = L − 0.1056·a − 0.0639·b = 0.227847
   s′ = L − 0.0895·a − 1.2915·b = 0.212531

4. 4. cube

   l = 0.229369³ = 0.012067
   m = 0.227847³ = 0.011829
   s = 0.212531³ = 0.009600

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.012287
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.012287
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.008022

6. 6. linear → sRGB, × 255

   R = 0.11373 × 255 = 29.00 → 29
   G = 0.11373 × 255 = 29.00 → 29
   B = 0.08627 × 255 = 22.00 → 22
