HSL to HEX: #FDE047

Result

Values are shown at full precision, so converting back gives exactly #fde047. 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 = 50.44°, S = 97.85%, L = 63.53%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.71372

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.60000   (H / 60° = 0.8407, sector 0)

4. 4. m

   m = L − C / 2 = 0.27844

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.71372, 0.60000, 0.00000)
   R = round((0.71372 + 0.27844) × 255) = 253
   G = round((0.60000 + 0.27844) × 255) = 224
   B = round((0.00000 + 0.27844) × 255) = 71
