Colored markers are writing instruments that contain ink in various colors. They typically have a felt tip or a brush tip, allowing for different line thicknesses and styles. These markers are commonly used for drawing, coloring, and labeling, making them popular in schools, offices, and art studios. The ink in colored markers can be water-based or permanent, affecting how they interact with different surfaces. Some markers are designed for specific uses, such as whiteboard markers for dry-erase boards or permanent markers for long-lasting marks. They come in a wide range of colors, enabling creativity and expression.
