oklch(0.51285 0.10995 163.565) → #007A55

Values are shown at full precision, so converting back gives exactly #007a55. 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(0.51285 0.10995 163.565)
```

2. OKLCH → Oklab

a = C·cos H = -0.10546
b = C·sin H = 0.03111

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.477766
m′ = L − 0.1056·a − 0.0639·b = 0.521996
s′ = L − 0.0895·a − 1.2915·b = 0.482111

4. cube

l = 0.477766³ = 0.109055
m = 0.521996³ = 0.142233
s = 0.482111³ = 0.112058

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000006
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.194617
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.090844

6. linear → sRGB, × 255

R = 0.00007 × 255 = 0.02 → 0
G = 0.47843 × 255 = 122.00 → 122
B = 0.33334 × 255 = 85.00 → 85

7. RGB → HEX
```
#007A55
```
