Step-by-step math

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

1. input
```
H = 149.88°, S = 100.00%, L = 50.00%
```
2. C
```
C = (1 − |2L − 1|) × S = 1.00000
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.49800   (H / 60° = 2.4980, sector 2)

4. m
```
m = L − C / 2 = 0.00000
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 1.00000, 0.49800)
R = round((0.00000 + 0.00000) × 255) = 0
G = round((1.00000 + 0.00000) × 255) = 255
B = round((0.49800 + 0.00000) × 255) = 127

6. RGB → HEX
```
#00FF7F
```
