OKLCH to HEX: #4F39F6

Result

Values are shown at full precision, so converting back gives exactly #4f39f6. 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(0.51015 0.26180 276.936)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.03162
   b = C·sin H = -0.25988

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.466596
   m′ = L − 0.1056·a − 0.0639·b = 0.523407
   s′ = L − 0.0895·a − 1.2915·b = 0.842957

4. 4. cube

   l = 0.466596³ = 0.101584
   m = 0.523407³ = 0.143390
   s = 0.842957³ = 0.598986

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.078185
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.040915
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.921548

6. 6. linear → sRGB, × 255

   R = 0.30980 × 255 = 79.00 → 79
   G = 0.22353 × 255 = 57.00 → 57
   B = 0.96469 × 255 = 246.00 → 246
