Step-by-step math

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

1. input
```
H = 25.00°, S = 5.26%, L = 44.71%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.04703
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.01960   (H / 60° = 0.4167, sector 0)

4. m
```
m = L − C / 2 = 0.42358
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.04703, 0.01960, 0.00000)
R = round((0.04703 + 0.42358) × 255) = 120
G = round((0.01960 + 0.42358) × 255) = 113
B = round((0.00000 + 0.42358) × 255) = 108

6. RGB → HEX
```
#78716C
```
