HSL to HEX: #005F78

Result

Values are shown at full precision, so converting back gives exactly #005f78. 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 = 192.50°, S = 100.00%, L = 23.53%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.47060

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.37256   (H / 60° = 3.2083, sector 3)

4. 4. m

   m = L − C / 2 = 0.00000

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.37256, 0.47060)
   R = round((0.00000 + 0.00000) × 255) = 0
   G = round((0.37256 + 0.00000) × 255) = 95
   B = round((0.47060 + 0.00000) × 255) = 120
