How it's used

Refers primarily to high-visibility colors or light-emitting properties rather than just any light. It is frequently used to describe stationery like highlighters or safety gear that stands out in low light. When talking about the actual insect, use 螢火蟲 instead of just the adjective.

Examples

This highlighter is very eye-catching.
Is your shirt a fluorescent color?

Common phrases

neon green

Common mistake

Avoid using this to describe things that are simply bright or shiny, as it specifically implies a neon or glowing quality. Do not confuse it with 閃光, which refers to a flash of light or something that sparkles.
