Step-by-step math

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

1. input
```
oklch(0.43834 0.21794 303.915)
```

2. OKLCH → Oklab

a = C·cos H = 0.12160
b = C·sin H = -0.18086

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.447505
m′ = L − 0.1056·a − 0.0639·b = 0.437052
s′ = L − 0.0895·a − 1.2915·b = 0.661038

4. cube

l = 0.447505³ = 0.089618
m = 0.437052³ = 0.083483
s = 0.661038³ = 0.288855

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.155926
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.005605
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.434152

6. linear → sRGB, × 255

R = 0.43137 × 255 = 110.00 → 110
G = 0.06666 × 255 = 17.00 → 17
B = 0.69020 × 255 = 176.00 → 176

7. RGB → HEX
```
#6E11B0
