Values are shown at full precision, so converting back gives exactly #510424. 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 = 335.06°, S = 90.59%, L = 16.67%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.30203

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.12554   (H / 60° = 5.5843, sector 5)

4. 4. m

   m = L − C / 2 = 0.01569

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.30203, 0.00000, 0.12554)
   R = round((0.30203 + 0.01569) × 255) = 81
   G = round((0.00000 + 0.01569) × 255) = 4
   B = round((0.12554 + 0.01569) × 255) = 36
