OKLCH to HEX: #881337

Result

Values are shown at full precision, so converting back gives exactly #881337. 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(0.41033 0.15017 10.272)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.14776
   b = C·sin H = 0.02678

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.474673
   m′ = L − 0.1056·a − 0.0639·b = 0.393022
   s′ = L − 0.0895·a − 1.2915·b = 0.362523

4. 4. cube

   l = 0.474673³ = 0.106951
   m = 0.393022³ = 0.060709
   s = 0.362523³ = 0.047644

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.246208
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.006513
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.038205

6. 6. linear → sRGB, × 255

   R = 0.53334 × 255 = 136.00 → 136
   G = 0.07451 × 255 = 19.00 → 19
   B = 0.21569 × 255 = 55.00 → 55
