There's no compelling reason for the blue buttons, and for the sake of consistency all jui buttons should look the same
It originally used normal jquery-ui buttons, but our user tests indicated that users did not notice the submit button, so they were colored blue to attract more attention. There are blue, red and green variants available for jquery-ui buttons, and are intended to be used when it makes sense.
Ok, this makes sense
