Step-by-step math

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

1. input
```
H = 20.00°, S = 14.29%, L = 4.12%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.01177
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00392   (H / 60° = 0.3333, sector 0)

4. m
```
m = L − C / 2 = 0.03531
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.01177, 0.00392, 0.00000)
R = round((0.01177 + 0.03531) × 255) = 12
G = round((0.00392 + 0.03531) × 255) = 10
B = round((0.00000 + 0.03531) × 255) = 9

6. RGB → HEX
```
#0C0A09
```
