Step-by-step math

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

1. input
```
H = 338.93°, S = 89.12%, L = 28.82%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.51369
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.18039   (H / 60° = 5.6488, sector 5)

4. m
```
m = L − C / 2 = 0.03136
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.51369, 0.00000, 0.18039)
R = round((0.51369 + 0.03136) × 255) = 139
G = round((0.00000 + 0.03136) × 255) = 8
B = round((0.18039 + 0.03136) × 255) = 54

6. RGB → HEX
```
#8B0836
```
