Step-by-step math

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

1. input
```
oklch(0.59987 0.00000 0.000)
```

2. OKLCH → Oklab

a = C·cos H = 0.00000
b = C·sin H = 0.00000

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.599870
m′ = L − 0.1056·a − 0.0639·b = 0.599870
s′ = L − 0.0895·a − 1.2915·b = 0.599870

4. cube

l = 0.599870³ = 0.215860
m = 0.599870³ = 0.215860
s = 0.599870³ = 0.215860

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.215860
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.215860
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.215860

6. linear → sRGB, × 255

R = 0.50196 × 255 = 128.00 → 128
G = 0.50196 × 255 = 128.00 → 128
B = 0.50196 × 255 = 128.00 → 128

7. RGB → HEX
