Election counts in the city where I work are special occasions, and I'm expected to photograph all but the most minor of them. The count is held in a ballroom in the Senior Center, a large room with a tan floor, red and cream-colored walls, green furniture, and bright incandescent lighting on dimmer switches. Getting the white balance right is a challenge, with almost every picture requiring individual attention.
At the count on Tuesday evening some of my pictures showed my other camera lying on a table with the City's 70-200mm f/2.8L IS II lens mounted. I discovered, more or less by accident, that the lens's color is a very good neutral grey and could often be used to set the white balance using the "click white balance" feature of Digital Photo Professional. I don't know whether Canon intended it that way, but it goes to show that one never knows to what uses one's equipment may be able to be put.

So THAT's why they paint them "white"! 😉
