What the Square Logo Colors Mean?
The Square logo colors are as literal as the name. The mark is a square, drawn first as a small green cube to echo the white card reader that plugs into a phone, then flattened to a black-and-white shape as the company grew past that one product. There is no color symbolism left in it.
Square Logo Color History
Square logo color history moves from the 2009 green cube to a cleaner black square around 2016, set with a custom sans underneath. Black and white have carried it since.
Square Logo Fonts
Square logo fonts are Square Sans, part of the Cash Sans family drawn in-house, not licensed. A neutral grotesque such as Helvetica is the everyday stand-in.
Square Logo JPG
Square logo in JPG. No transparency, so it is flattened onto white. Safe for documents and slide decks.
Square Logo PNG
Square logo in PNG, with a transparent background. Use it over a colored surface.
Square Logo WebP
Square logo in WebP. Same transparency as the PNG at about a third of the file size.
Square Color Code Shades
Square color code shades step evenly from the primary toward black, for hover states, borders and shadows.
These are interface steps, not Square paint or trim names.

Brand colors are chosen for recognition, not for legibility. A failing value here is normal. It means use it as a fill, not as text.
