 *
 * Teal #2F99A4 reaches only 3.38:1 on white, so it is used for large text, fills
 * and borders only. Body-size teal text uses #15585E (8.1:1) and teal fills
 * carrying normal-size white text use #257880 (5.2:1). The accent #FF4D00 is
 * 3.32:1 on white and 3.12:1 on the alpha banner's tint, so accent-coloured
 * text uses #9A2E00 (7.1:1 and 7.6:1). Same hues throughout; only the
 * luminance changes.
