Values are shown at full precision, so converting back gives exactly #4ade80. 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. input
```
oklch(0.80035 0.18206 151.711)
```

2. OKLCH → Oklab

a = C·cos H = -0.16032
b = C·sin H = 0.08628

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.755431
m′ = L − 0.1056·a − 0.0639·b = 0.811764
s′ = L − 0.0895·a − 1.2915·b = 0.703264

4. cube

l = 0.755431³ = 0.431106
m = 0.811764³ = 0.534920
s = 0.703264³ = 0.347821

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.068480
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.730463
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.215862

6. linear → sRGB, × 255

R = 0.29020 × 255 = 74.00 → 74
G = 0.87059 × 255 = 222.00 → 222
B = 0.50196 × 255 = 128.00 → 128

7. RGB → HEX
```
#4ADE80
