The change of the seasons brings autumn colour. Here we see the relief decorated concrete wall of a UVic parking garage with the oak leaves that inspired the motif.

Due to the tilt of the Earth's rotation axis with respect to its orbit around the sun, seasonal change is the main defining characteristic of climate in mid to high latitude regions.

For more information on the chemistry of coloured leaves see the image included below (from Compound Interest).
