Step-by-step math

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

1. input
```
H = 33.33°, S = 5.45%, L = 32.35%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.03526
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.01959   (H / 60° = 0.5555, sector 0)

4. m
```
m = L − C / 2 = 0.30587
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.03526, 0.01959, 0.00000)
R = round((0.03526 + 0.30587) × 255) = 87
G = round((0.01959 + 0.30587) × 255) = 83
B = round((0.00000 + 0.30587) × 255) = 78

6. RGB → HEX
```
#57534E
```
