Step-by-step math

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

1. input
```
oklch(0.12985 0.04253 265.132)
```

2. OKLCH → Oklab

a = C·cos H = -0.00361
b = C·sin H = -0.04238

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.119275
m′ = L − 0.1056·a − 0.0639·b = 0.132937
s′ = L − 0.0895·a − 1.2915·b = 0.184902

4. cube

l = 0.119275³ = 0.001697
m = 0.132937³ = 0.002349
s = 0.184902³ = 0.006322

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000607
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.001821
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.009135

6. linear → sRGB, × 255

R = 0.00784 × 255 = 2.00 → 2
G = 0.02353 × 255 = 6.00 → 6
B = 0.09412 × 255 = 24.00 → 24

7. RGB → HEX
```
#020618
