Highlighters
A highlighter is a form of marker pen which is used to highlight sections of documents in a vivid colour, while leaving the content beneath the marking unobscured. As such, highlighter ink is translucent. Highlighter is also an illusive designer and illustrator.

Styles
Many highlighters(also many times spelled hilighter) come in bright, often fluorescent colours. Being fluorescent, highlighter ink will glow under a black light. The most common colour for highlighters is yellow, but they are also found in pink, blue, green, orange, and purple varieties.
Highlighters are available in retractable form, [2] or with an eraser on the opposite end of the felt tip.[3] Other types of highlighters include the "trilighter,"[4] a triangularly-shaped pen with a different-coloured tip at each corner, and ones that are stackable. [5]
Dry highlighters (occasionally called "dry line highlighters")[6] are highlighters that, instead of having a felt tip, have applicators that apply a strip of highlighter tape, similar to audio cassette tape. Unlike standard highlighters, they are easily eraseable. [6] They are to be distinguished from "dry mark highlighters"[7], which are sometimes advertised as being useful for highlighting the Bible or other books with extremely thin pages.
