OKLCH to HEX: #B0C4DE

Result

Values are shown at full precision, so converting back gives exactly #b0c4de. 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(0.81362 0.04281 255.033)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.01106
   b = C·sin H = -0.04136

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.800313
   m′ = L − 0.1056·a − 0.0639·b = 0.817428
   s′ = L − 0.0895·a − 1.2915·b = 0.868022

4. 4. cube

   l = 0.800313³ = 0.512601
   m = 0.817428³ = 0.546196
   s = 0.868022³ = 0.654022

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.434142
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.552006
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.730463

6. 6. linear → sRGB, × 255

   R = 0.69019 × 255 = 176.00 → 176
   G = 0.76862 × 255 = 196.00 → 196
   B = 0.87059 × 255 = 222.00 → 222

7. 7. RGB → HEX
