Step-by-step math

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

1. input
```
H = 224.00°, S = 71.43%, L = 4.12%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.05886
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.01570   (H / 60° = 3.7333, sector 3)

4. m
```
m = L − C / 2 = 0.01177
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.01570, 0.05886)
R = round((0.00000 + 0.01177) × 255) = 3
G = round((0.01570 + 0.01177) × 255) = 7
B = round((0.05886 + 0.01177) × 255) = 18

6. RGB → HEX
```
#030712
```
