HSL to HEX: #FBBF24

Result

Values are shown at full precision, so converting back gives exactly #fbbf24. 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 = 43.26°, S = 96.41%, L = 56.27%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.84320

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.60795   (H / 60° = 0.7210, sector 0)

4. 4. m

   m = L − C / 2 = 0.14110

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.84320, 0.60795, 0.00000)
   R = round((0.84320 + 0.14110) × 255) = 251
   G = round((0.60795 + 0.14110) × 255) = 191
   B = round((0.00000 + 0.14110) × 255) = 36
