In our household the days growing longer and cooler triggers the mental transition from fall to winter.
The holidays and days of remembrance change color codes from the browns, oranges, and purples of fall and Día de los muertos to the blue and white of Hannukah accompanied by the green, red, white and black of Christmas and Kwanzaa.
We also have purple. The forty days of Advent need their due.
It shouldn't have surprised me to look at my counter and see the transition there, too. Fall enough to save the seeds and cool enough to make my daily plans around times needed for baking.
Hope you're enjoying the change in the weather at this time of year.
