Russet

A project to track colour changes over the course of a year.

The rough plan:

• Set up a Raspberry Pi with a camera, and point it out my window.

• Take pictures of the view, say once an hour. This will include a bunch of trees plus some sky.

• Downsample (is that the right word?) the picture:

  • Bucket the colours
  • Figure out how much of the image is covered by those colors (Example: 10% white, 5% grey, 20% brown, 40% deep green, 25% light green)

• Track those changes visually, over the course of a year, through a graph of some kind.
