Want a square with a custom color and size? Append size and color query parameters. Then just right-click on the square and choose "copy image". Colors are given without the "#", so black is "000000", not "#000000".
Here is your square with size and color .
Here are some awesome examples from Pantone's Color of the Year selections.
Hacktoberfest Squares
