Step-by-step math

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

1. input
```
H = 240.00°, S = 5.20%, L = 33.92%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.03528
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00000   (H / 60° = 4.0000, sector 4)

4. m
```
m = L − C / 2 = 0.32156
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.00000, 0.03528)
R = round((0.00000 + 0.32156) × 255) = 82
G = round((0.00000 + 0.32156) × 255) = 82
B = round((0.03528 + 0.32156) × 255) = 91

6. RGB → HEX
```
#52525B
```
