Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. input
```
oklch(0.56018 0.02107 213.503)
```

2. OKLCH → Oklab

a = C·cos H = -0.01757
b = C·sin H = -0.01163

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.550707
m′ = L − 0.1056·a − 0.0639·b = 0.562777
s′ = L − 0.0895·a − 1.2915·b = 0.576772

4. cube

l = 0.550707³ = 0.167017
m = 0.562777³ = 0.178242
s = 0.576772³ = 0.191873

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.135630
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.187827
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.201565

6. linear → sRGB, × 255

R = 0.40392 × 255 = 103.00 → 103
G = 0.47060 × 255 = 120.00 → 120
B = 0.48628 × 255 = 124.00 → 124

7. RGB → HEX
```
