Step-by-step math

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

1. input
```
H = 21.71°, S = 77.78%, L = 26.47%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.41177
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.14899   (H / 60° = 0.3618, sector 0)

4. m
```
m = L − C / 2 = 0.05882
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.41177, 0.14899, 0.00000)
R = round((0.41177 + 0.05882) × 255) = 120
G = round((0.14899 + 0.05882) × 255) = 53
B = round((0.00000 + 0.05882) × 255) = 15

6. RGB → HEX
```
#78350F
```
