A color picker is a tool that allows users to select and identify specific colors from a color palette, image, or other color-related source. This tool is commonly used by designers, artists, and web developers to choose and match colors for their projects, such as website design, graphics, and branding. Color pickers usually provide a range of color models (e.g. RGB, HEX, HSL) and often come with additional features such as color mixing, color history, and color saving.
