OKLCH to HEX: #831843

Result

Values are shown at full precision, so converting back gives exactly #831843. 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(0.40782 0.14418 2.432)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.14405
   b = C·sin H = 0.00612

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.466233
   m′ = L − 0.1056·a − 0.0639·b = 0.392223
   s′ = L − 0.0895·a − 1.2915·b = 0.387028

4. 4. cube

   l = 0.466233³ = 0.101346
   m = 0.392223³ = 0.060339
   s = 0.387028³ = 0.057973

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.226969
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.009132
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.056127

6. 6. linear → sRGB, × 255

   R = 0.51373 × 255 = 131.00 → 131
   G = 0.09410 × 255 = 24.00 → 24
   B = 0.26274 × 255 = 67.00 → 67
