HSL to HEX: #F3F4F6

Result

Values are shown at full precision, so converting back gives exactly #f3f4f6. 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 = 220.00°, S = 14.29%, L = 95.88%

2. 2. C

   C = (1 − |2L − 1|) × S = 0.01177

3. 3. X

   X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.00392   (H / 60° = 3.6667, sector 3)

4. 4. m

   m = L − C / 2 = 0.95291

5. 5. (R′, G′, B′) + m

   (R′, G′, B′) = (0.00000, 0.00392, 0.01177)
   R = round((0.00000 + 0.95291) × 255) = 243
   G = round((0.00392 + 0.95291) × 255) = 244
   B = round((0.01177 + 0.95291) × 255) = 246
