Where should modal buttons be placed?

In modals and dialogs, align the buttons to the right, or possibly consider a center alignment. Rationale: all major platforms (Windows & macOS) right-align the terminating actions buttons in modals/dialogs, users scan modals in a “Z” pattern (check out the “Gutenberg Diagram”).

Why are delete buttons red?

When designers use red for delete buttons, the color naturally gives users pause due to its connotations. Both deletion of a file or closing an account are good examples of using red in design.
