Step-by-step math

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

1. input
```
H = 181.85°, S = 25.49%, L = 50.00%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.25490
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.24704   (H / 60° = 3.0308, sector 3)

4. m
```
m = L − C / 2 = 0.37255
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.24704, 0.25490)
R = round((0.00000 + 0.37255) × 255) = 95
G = round((0.24704 + 0.37255) × 255) = 158
B = round((0.25490 + 0.37255) × 255) = 160

6. RGB → HEX
```
#5F9EA0
```
