Step-by-step math

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

1. input
```
H = 215.00°, S = 13.79%, L = 34.12%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.09410
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.03921   (H / 60° = 3.5833, sector 3)

4. m
```
m = L − C / 2 = 0.29415
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.03921, 0.09410)
R = round((0.00000 + 0.29415) × 255) = 75
G = round((0.03921 + 0.29415) × 255) = 85
B = round((0.09410 + 0.29415) × 255) = 99

6. RGB → HEX
```
#4B5563
```
