Sonic the Hedgehog's 30th anniversary logo starts with a large number 30 in red. With a white outline on that number followed by a blue outline, they gave the number added weight and a color that could blend neatly into a blue silhouette of their famous character above. At the bottom, the word "anniversary" in that same blue clarifies the meaning of the number and balances the red with blue above and below.
