BackOffice is a light, calm, white-surfaced brand. Color is spent like money — rarely and deliberately. When it appears, it's the teal-to-aqua gradient, and it means "this is the point."
Marketing surfaces use the top row; the product UI uses the bottom row for record status. Functional colors are for state — never for decoration.
On any surface we design, roughly nine-tenths is neutral. If a layout feels colorful, it's off-brand.
| Pair | Ratio | Verdict |
|---|---|---|
| Ink on White | ~18 : 1 | AAA — default for all text. |
| Muted on White | ~6 : 1 | AA — fine for secondary text ≥ 13px. |
| White on Night | ~19 : 1 | AAA — dark bands and cards. |
| White on Teal | ~4.8 : 1 | Large/bold text only — buttons and headlines, never body copy. |
| Ink on Aqua | ~10.1 : 1 | AAA — if text must sit on aqua, it's ink, never white. |
| White on the gradient | varies | Allowed only ≥ 14px semibold (buttons, stat numerals) — the aqua end is the constraint. |
