Step-by-step math

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

1. input
```
oklch(0.38018 0.17611 304.783)
```

2. OKLCH → Oklab

a = C·cos H = 0.10047
b = C·sin H = -0.14464

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.388784
m′ = L − 0.1056·a − 0.0639·b = 0.378811
s′ = L − 0.0895·a − 1.2915·b = 0.557994

4. cube

l = 0.388784³ = 0.058766
m = 0.378811³ = 0.054358
s = 0.557994³ = 0.173735

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.099899
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.008022
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.258189

6. linear → sRGB, × 255

R = 0.34902 × 255 = 89.00 → 89
G = 0.08627 × 255 = 22.00 → 22
B = 0.54510 × 255 = 139.00 → 139

7. RGB → HEX
```
#59168B
