The color changes that occur in leaves in this area of the world are caused by the leaves responding to colder temperatures and the decrease in light.  The veins of leaves are their vascular system.  Wikipedea has a very interesting entry on "leaf".  Here is a small part of that entry:

Veins

The veins are made up of:

The veins are the vascular tissue of the leaf and are located in the spongy layer of the mesophyll. They are typical examples of pattern formation through ramification. The pattern of the veins is called venation.

• Xylem: tubes that bring water and minerals from the roots into the leaf.
• Phloem: tubes that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf.
