OKLCH to HEX: #4C0519

Result

Values are shown at full precision, so converting back gives exactly #4c0519. 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(0.27085 0.10086 12.094)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.09862
   b = C·sin H = 0.02113

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.314498
   m′ = L − 0.1056·a − 0.0639·b = 0.259090
   s′ = L − 0.0895·a − 1.2915·b = 0.234734

4. 4. cube

   l = 0.314498³ = 0.031107
   m = 0.259090³ = 0.017392
   s = 0.234734³ = 0.012934

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.072273
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.001518
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.009721

6. 6. linear → sRGB, × 255

   R = 0.29804 × 255 = 76.00 → 76
   G = 0.01961 × 255 = 5.00 → 5
   B = 0.09804 × 255 = 25.00 → 25

7. 7. RGB → HEX
