HSL to HEX: #F8FAFC

Result

Values are shown at full precision, so converting back gives exactly #f8fafc. 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 = 210.00°, S = 40.00%, L = 98.04%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.01568

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00784   (H / 60° = 3.5000, sector 3)

4. 4. m

   m = L − C / 2 = 0.97256

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.00784, 0.01568)
   R = round((0.00000 + 0.97256) × 255) = 248
   G = round((0.00784 + 0.97256) × 255) = 250
   B = round((0.01568 + 0.97256) × 255) = 252
