OKLCH to HEX: #8B4513

Result

Values are shown at full precision, so converting back gives exactly #8b4513. 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(0.47078 0.11214 50.845)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.07081
   b = C·sin H = 0.08696

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.517610
   m′ = L − 0.1056·a − 0.0639·b = 0.457753
   s′ = L − 0.0895·a − 1.2915·b = 0.352139

4. 4. cube

   l = 0.517610³ = 0.138678
   m = 0.457753³ = 0.095916
   s = 0.352139³ = 0.043666

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.258175
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.059511
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.006513

6. 6. linear → sRGB, × 255

   R = 0.54509 × 255 = 139.00 → 139
   G = 0.27059 × 255 = 69.00 → 69
   B = 0.07452 × 255 = 19.00 → 19
