Step-by-step math

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

1. input
```
H = 271.15°, S = 75.93%, L = 52.75%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.71754
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.37252   (H / 60° = 4.5192, sector 4)

4. m
```
m = L − C / 2 = 0.16873
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.37252, 0.00000, 0.71754)
R = round((0.37252 + 0.16873) × 255) = 138
G = round((0.00000 + 0.16873) × 255) = 43
B = round((0.71754 + 0.16873) × 255) = 226

6. RGB → HEX
```
#8A2BE2
```
