Step-by-step math

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

1. input
```
oklch(0.30181 0.05407 229.695)
```

2. OKLCH → Oklab

a = C·cos H = -0.03498
b = C·sin H = -0.04123

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.279049
m′ = L − 0.1056·a − 0.0639·b = 0.308135
s′ = L − 0.0895·a − 1.2915·b = 0.358193

4. cube

l = 0.279049³ = 0.021729
m = 0.308135³ = 0.029257
s = 0.358193³ = 0.045957

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.002427
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.033104
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.057806

6. linear → sRGB, × 255

R = 0.03135 × 255 = 7.99 → 8
G = 0.20000 × 255 = 51.00 → 51
B = 0.26667 × 255 = 68.00 → 68

7. RGB → HEX
```
#083344
