Primary: cta blue conveys a sense of trust, reliability, and familiarity. This color was chosen because of it’s contrast to white (for labels and icons) as well as the commonality with current web experience trends.

Secondary: a derivative of primary, it includes the same coloring as the primary button, but in an outline form. The click behavior inverts the button, for greater user understanding that their command has been received.

Tertiary: the text button. For use with low emphasis actions. When used as a hyperlink, it’s a best practice to have underlined text. When used in a modal as a simple action, underline is not necessary (but use context to determine if the information scent is high enough without it).
