OKLCH to HEX: #F5FFFA

Result

Values are shown at full precision, so converting back gives exactly #f5fffa. 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(0.99117 0.01237 164.813)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.01194
   b = C·sin H = 0.00324

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.987138
   m′ = L − 0.1056·a − 0.0639·b = 0.992223
   s′ = L − 0.0895·a − 1.2915·b = 0.988053

4. 4. cube

   l = 0.987138³ = 0.961908
   m = 0.992223³ = 0.976851
   s = 0.988053³ = 0.964586

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.913099
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.999991
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.955970

6. 6. linear → sRGB, × 255

   R = 0.96078 × 255 = 245.00 → 245
   G = 1.00000 × 255 = 255.00 → 255
   B = 0.98039 × 255 = 250.00 → 250

7. 7. RGB → HEX
