OKLCH to HEX: #432004

Result

Values are shown at full precision, so converting back gives exactly #432004. 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(0.28709 0.06625 54.588)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.03839
   b = C·sin H = 0.05399

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.313957
   m′ = L − 0.1056·a − 0.0639·b = 0.279590
   s′ = L − 0.0895·a − 1.2915·b = 0.213922

4. 4. cube

   l = 0.313957³ = 0.030946
   m = 0.279590³ = 0.021856
   s = 0.213922³ = 0.009790

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.056129
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.014443
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.001213

6. 6. linear → sRGB, × 255

   R = 0.26275 × 255 = 67.00 → 67
   G = 0.12549 × 255 = 32.00 → 32
   B = 0.01568 × 255 = 4.00 → 4
