Step-by-step math

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

1. input
```
H = 40.61°, S = 96.12%, L = 40.39%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.77646
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.52553   (H / 60° = 0.6768, sector 0)

4. m
```
m = L − C / 2 = 0.01567
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.77646, 0.52553, 0.00000)
R = round((0.77646 + 0.01567) × 255) = 202
G = round((0.52553 + 0.01567) × 255) = 138
B = round((0.00000 + 0.01567) × 255) = 4

6. RGB → HEX
```
#CA8A04
```
