Step-by-step math

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

1. input
```
oklch(0.42152 0.09515 57.939)
```

2. OKLCH → Oklab

a = C·cos H = 0.05051
b = C·sin H = 0.08064

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.458940
m′ = L − 0.1056·a − 0.0639·b = 0.411039
s′ = L − 0.0895·a − 1.2915·b = 0.312857

4. cube

l = 0.458940³ = 0.096665
m = 0.411039³ = 0.069446
s = 0.312857³ = 0.030622

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.171441
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.048173
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.003036

6. linear → sRGB, × 255

R = 0.45098 × 255 = 115.00 → 115
G = 0.24314 × 255 = 62.00 → 62
B = 0.03922 × 255 = 10.00 → 10

7. RGB → HEX
```
#733E0A
