OKLCH to HEX: #67E8F9

Result

Values are shown at full precision, so converting back gives exactly #67e8f9. 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(0.86507 0.11535 207.078)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.10271
   b = C·sin H = -0.05251

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.813032
   m′ = L − 0.1056·a − 0.0639·b = 0.879265
   s′ = L − 0.0895·a − 1.2915·b = 0.942073

4. 4. cube

   l = 0.813032³ = 0.537432
   m = 0.879265³ = 0.679765
   s = 0.942073³ = 0.836093

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.135616
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.806948
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.947309

6. 6. linear → sRGB, × 255

   R = 0.40390 × 255 = 102.99 → 103
   G = 0.90980 × 255 = 232.00 → 232
   B = 0.97647 × 255 = 249.00 → 249
