Step-by-step math

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

1. input
```
oklch(0.43502 0.02938 321.775)
```

2. OKLCH → Oklab

a = C·cos H = 0.02308
b = C·sin H = -0.01818

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.440245
m′ = L − 0.1056·a − 0.0639·b = 0.433744
s′ = L − 0.0895·a − 1.2915·b = 0.456432

4. cube

l = 0.440245³ = 0.085326
m = 0.433744³ = 0.081602
s = 0.456432³ = 0.095089

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.099899
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.072275
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.104617

6. linear → sRGB, × 255

R = 0.34902 × 255 = 89.00 → 89
G = 0.29805 × 255 = 76.00 → 76
B = 0.35686 × 255 = 91.00 → 91

7. RGB → HEX
```
#594C5B
