Step-by-step math

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

1. input
```
oklch(0.58066 0.12658 109.769)
```

2. OKLCH → Oklab

a = C·cos H = -0.04281
b = C·sin H = 0.11912

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.589398
m′ = L − 0.1056·a − 0.0639·b = 0.577573
s′ = L − 0.0895·a − 1.2915·b = 0.430649

4. cube

l = 0.589398³ = 0.204751
m = 0.577573³ = 0.192673
s = 0.430649³ = 0.079868

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.215858
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.215855
B = −0.0042·l − 0.7034·m + 1.7076·s = -0.000005

6. linear → sRGB, × 255

R = 0.50196 × 255 = 128.00 → 128
G = 0.50196 × 255 = 128.00 → 128
B = 0.00000 × 255 = 0.00 → 0

7. RGB → HEX
```
#808000
