Step-by-step math

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

1. input
```
H = 218.18°, S = 13.58%, L = 84.12%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.04313
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.01568   (H / 60° = 3.6363, sector 3)

4. m
```
m = L − C / 2 = 0.81963
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.01568, 0.04313)
R = round((0.00000 + 0.81963) × 255) = 209
G = round((0.01568 + 0.81963) × 255) = 213
B = round((0.04313 + 0.81963) × 255) = 220

6. RGB → HEX
```
#D1D5DC
```
