OKLCH to HEX: #3CB371

Result

Values are shown at full precision, so converting back gives exactly #3cb371. 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(0.68404 0.14402 154.999)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.13053
   b = C·sin H = 0.06087

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.645443
   m′ = L − 0.1056·a − 0.0639·b = 0.693932
   s′ = L − 0.0895·a − 1.2915·b = 0.617110

4. 4. cube

   l = 0.645443³ = 0.268890
   m = 0.693932³ = 0.334157
   s = 0.617110³ = 0.235011

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.045180
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.450784
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.165128

6. 6. linear → sRGB, × 255

   R = 0.23528 × 255 = 60.00 → 60
   G = 0.70196 × 255 = 179.00 → 179
   B = 0.44313 × 255 = 113.00 → 113

7. 7. RGB → HEX
