Step-by-step math

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

1. input
```
oklch(0.42100 0.08970 57.708)
```

2. OKLCH → Oklab

a = C·cos H = 0.04792
b = C·sin H = 0.07583

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.456357
m′ = L − 0.1056·a − 0.0639·b = 0.411100
s′ = L − 0.0895·a − 1.2915·b = 0.318783

4. cube

l = 0.456357³ = 0.095041
m = 0.411100³ = 0.069477
s = 0.318783³ = 0.032395

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.165132
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.049707
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.006049

6. linear → sRGB, × 255

R = 0.44314 × 255 = 113.00 → 113
G = 0.24706 × 255 = 63.00 → 63
B = 0.07059 × 255 = 18.00 → 18

7. RGB → HEX
```
#713F12
