Different Shades of Green

Interstate 8 at California 163 in San Diego

The newer, highly reflective signs for California freeway signs has a different shade of green than the old-style signs with button reflectors. The new signs also indicate exit numbers, so you can see that the highly reflective signs here are for California 163, exiting from Interstate 8 near the Hotel Circle area of San Diego. The older-style sign is the one on the left for Mission Center Road.
