OKLCH to HEX: #1A2E05

Result

Values are shown at full precision, so converting back gives exactly #1a2e05. 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(0.27406 0.06880 132.109)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.04613
   b = C·sin H = 0.05104

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.266790
   m′ = L − 0.1056·a − 0.0639·b = 0.275671
   s′ = L − 0.0895·a − 1.2915·b = 0.212270

4. 4. cube

   l = 0.266790³ = 0.018989
   m = 0.275671³ = 0.020949
   s = 0.212270³ = 0.009565

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.010329
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.027321
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.001517

6. 6. linear → sRGB, × 255

   R = 0.10196 × 255 = 26.00 → 26
   G = 0.18039 × 255 = 46.00 → 46
   B = 0.01960 × 255 = 5.00 → 5
