HSL to HEX: #0C4A6E

Result

Values are shown at full precision, so converting back gives exactly #0c4a6e. 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 = 202.04°, S = 80.33%, L = 23.92%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.38430

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.24313   (H / 60° = 3.3673, sector 3)

4. 4. m

   m = L − C / 2 = 0.04705

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.24313, 0.38430)
   R = round((0.00000 + 0.04705) × 255) = 12
   G = round((0.24313 + 0.04705) × 255) = 74
   B = round((0.38430 + 0.04705) × 255) = 110
