Step-by-step math

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

1. input
```
H = 226.88°, S = 59.26%, L = 21.18%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.25103
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.05489   (H / 60° = 3.7813, sector 3)

4. m
```
m = L − C / 2 = 0.08629
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.05489, 0.25103)
R = round((0.00000 + 0.08629) × 255) = 22
G = round((0.05489 + 0.08629) × 255) = 36
B = round((0.25103 + 0.08629) × 255) = 86

6. RGB → HEX
```
#162456
```
