Step-by-step math

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

1. input
```
H = 0.00°, S = 0.00%, L = 50.20%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.00000
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00000   (H / 60° = 0.0000, sector 0)

4. m
```
m = L − C / 2 = 0.50200
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.00000, 0.00000)
R = round((0.00000 + 0.50200) × 255) = 128
G = round((0.00000 + 0.50200) × 255) = 128
B = round((0.00000 + 0.50200) × 255) = 128

6. RGB → HEX
```
#808080
