Step-by-step math

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

1. input
```
H = 25.96°, S = 90.48%, L = 37.06%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.67064
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.29016   (H / 60° = 0.4327, sector 0)

4. m
```
m = L − C / 2 = 0.03528
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.67064, 0.29016, 0.00000)
R = round((0.67064 + 0.03528) × 255) = 180
G = round((0.29016 + 0.03528) × 255) = 83
B = round((0.00000 + 0.03528) × 255) = 9

6. RGB → HEX
```
#B45309
```
