Step-by-step math

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

1. input
```
H = 200.41°, S = 98.01%, L = 39.41%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.77251
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.50973   (H / 60° = 3.3402, sector 3)

4. m
```
m = L − C / 2 = 0.00784
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.50973, 0.77251)
R = round((0.00000 + 0.00784) × 255) = 2
G = round((0.50973 + 0.00784) × 255) = 132
B = round((0.77251 + 0.00784) × 255) = 199

6. RGB → HEX
```
#0284C7
```
