Red Yellow Blue Green
Google colors, or Apple? As WWDC 2014 starts in San Francisco, I noticed that the Apple billboards along the US 101 / I-80 corridor in the heart of San Francisco are all iPhone 5c "fan" design, with the colors in the order red, yellow, blue, and green.

The heart of the Google logo? Red, yellow, blue, green.

The Chrome logo has the same colors, too.

An interesting coincidence, don't you think?

These eight billboard photos were taken along a 3.5 mile stretch of freeway, from US 101 exit 431 to I-80 exit 2B, on June 1, 2014. This is the stretch of freeway that gets you from anywhere else to Moscone Center, where Apple is holding WWDC 2014. The Google and Chrome logos are included for comparison.

Apple is running iPhone 5c billboards in the same series in Los Angeles. The Daily Billboard blog has great photos of them here:
