Step-by-step math

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

1. input
```
H = 274.36°, S = 72.67%, L = 31.57%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.45884
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.26276   (H / 60° = 4.5727, sector 4)

4. m
```
m = L − C / 2 = 0.08628
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.26276, 0.00000, 0.45884)
R = round((0.26276 + 0.08628) × 255) = 89
G = round((0.00000 + 0.08628) × 255) = 22
B = round((0.45884 + 0.08628) × 255) = 139

6. RGB → HEX
```
#59168B
```
