HSL to HEX: #DC143C

Result

Values are shown at full precision, so converting back gives exactly #dc143c. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. 1. input

   H = 348.00°, S = 83.33%, L = 47.06%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.78430

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.15686   (H / 60° = 5.8000, sector 5)

4. 4. m

   m = L − C / 2 = 0.07845

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.78430, 0.00000, 0.15686)
   R = round((0.78430 + 0.07845) × 255) = 220
   G = round((0.00000 + 0.07845) × 255) = 20
   B = round((0.15686 + 0.07845) × 255) = 60
