Yellow is the brightest colour the eye sees, so yellow logos are built to be noticed from a distance. It signals optimism and value, and it often appears on dark or black backgrounds to keep the contrast strong.
Below are 192 brands whose main colour is yellow, including McDonald's and Shell. Every logo links to a page with free SVG and PNG downloads and its exact colour codes.
