HSL to HEX: #2F4F4F

Result

Values are shown at full precision, so converting back gives exactly #2f4f4f. 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 = 180.00°, S = 25.40%, L = 24.71%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.12553

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.12553   (H / 60° = 3.0000, sector 3)

4. 4. m

   m = L − C / 2 = 0.18434

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.12553, 0.12553)
   R = round((0.00000 + 0.18434) × 255) = 47
   G = round((0.12553 + 0.18434) × 255) = 79
   B = round((0.12553 + 0.18434) × 255) = 79
