Bright on dark, like neon signage over a midnight street. Apricot Orange and Olive Yellow glow against Deep Indigo, which is almost black with a hint of navy. The effect is retro and nocturnal, recalling a jazz-club matchbook from the eighties. Use it for dark-mode interfaces, music branding or event posters; orange on indigo is easy to read, so it handles real text as well as accents.
