Step-by-step math

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

1. input
```
oklch(0.62558 0.20244 319.226)
```

2. OKLCH → Oklab

a = C·cos H = 0.15331
b = C·sin H = -0.13221

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.657810
m′ = L − 0.1056·a − 0.0639·b = 0.617839
s′ = L − 0.0895·a − 1.2915·b = 0.782607

4. cube

l = 0.657810³ = 0.284643
m = 0.617839³ = 0.235844
s = 0.782607³ = 0.479327

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.491022
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.090841
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.651414

6. linear → sRGB, × 255

R = 0.72941 × 255 = 186.00 → 186
G = 0.33333 × 255 = 85.00 → 85
B = 0.82746 × 255 = 211.00 → 211

7. RGB → HEX
```
#BA55D3
