Step-by-step math

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

1. input
```
oklch(0.44614 0.02982 257.680)
```

2. OKLCH → Oklab

a = C·cos H = -0.00636
b = C·sin H = -0.02913

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.437331
m′ = L − 0.1056·a − 0.0639·b = 0.448672
s′ = L − 0.0895·a − 1.2915·b = 0.484335

4. cube

l = 0.437331³ = 0.083643
m = 0.448672³ = 0.090321
s = 0.484335³ = 0.113615

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.068479
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.090839
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.130127

6. linear → sRGB, × 255

R = 0.29020 × 255 = 74.00 → 74
G = 0.33333 × 255 = 85.00 → 85
B = 0.39606 × 255 = 101.00 → 101

7. RGB → HEX
```
#4A5565
