Step-by-step math

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

1. input
```
oklch(0.54111 0.22724 311.509)
```

2. OKLCH → Oklab

a = C·cos H = 0.15060
b = C·sin H = -0.17017

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.564076
m′ = L − 0.1056·a − 0.0639·b = 0.536078
s′ = L − 0.0895·a − 1.2915·b = 0.747404

4. cube

l = 0.564076³ = 0.179478
m = 0.536078³ = 0.154058
s = 0.747404³ = 0.417510

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.318539
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.031893
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.603826

6. linear → sRGB, × 255

R = 0.59999 × 255 = 153.00 → 153
G = 0.19607 × 255 = 50.00 → 50
B = 0.80000 × 255 = 204.00 → 204

7. RGB → HEX
```
