Most website navigation systems rely on words. Terms like Products, Industries, and About Us have become standard; many companies have such phrases or subtle variants on their websites. Other labels are more particular to each company or industry. But in general, website navigation systems are primarily verbal.
Some websites break that norm. Color Palettes is an interesting example.
As you may have surmised, this site’s navigation uses colored tiles instead of words. It also has two modes, one of which adds a useful bit of functionality.
I love examining unusual navigation systems. Have you seen a website or app that implements interesting ways for users to move around? Please let me know.
