Step-by-step math

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

1. input
```
oklch(0.44411 0.01096 78.213)
```

2. OKLCH → Oklab

a = C·cos H = 0.00224
b = C·sin H = 0.01073

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.447313
m′ = L − 0.1056·a − 0.0639·b = 0.443189
s′ = L − 0.0895·a − 1.2915·b = 0.430053

4. cube

l = 0.447313³ = 0.089502
m = 0.443189³ = 0.087049
s = 0.430053³ = 0.079537

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.095314
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.086502
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.074210

6. linear → sRGB, × 255

R = 0.34119 × 255 = 87.00 → 87
G = 0.32549 × 255 = 83.00 → 83
B = 0.30195 × 255 = 77.00 → 77

7. RGB → HEX
```
