HSL to HEX: #9F9FA9

Result

Values are shown at full precision, so converting back gives exactly #9f9fa9. 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 = 240.00°, S = 5.49%, L = 64.31%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.03919

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00000   (H / 60° = 4.0000, sector 4)

4. 4. m

   m = L − C / 2 = 0.62351

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.00000, 0.03919)
   R = round((0.00000 + 0.62351) × 255) = 159
   G = round((0.00000 + 0.62351) × 255) = 159
   B = round((0.03919 + 0.62351) × 255) = 169
