OKLCH to HEX: #FF2056

Result

Values are shown at full precision, so converting back gives exactly #ff2056. 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(0.64349 0.24521 16.501)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.23511
   b = C·sin H = 0.06965

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.751704
   m′ = L − 0.1056·a − 0.0639·b = 0.614224
   s′ = L − 0.0895·a − 1.2915·b = 0.532503

4. 4. cube

   l = 0.751704³ = 0.424756
   m = 0.614224³ = 0.231729
   s = 0.532503³ = 0.150996

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 1.000004
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.014442
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.093058

6. 6. linear → sRGB, × 255

   R = 1.00000 × 255 = 255.00 → 255
   G = 0.12548 × 255 = 32.00 → 32
   B = 0.33725 × 255 = 86.00 → 86

7. 7. RGB → HEX
