1. What Is a Color Picker? A color picker is a digital tool that lets you choose an exact color and see its codes in formats like HEX, RGB, or HSL. You can think of it as: A color chooser: you move a slider, use a color wheel picker, or type a value. A color identifier: you click on a pixel, and it tells you the color code. A color finder: you search for a color that matches your design or brand. Modern color pickers often support: RGB color picker: shows values like RGB(34, 120, 200) . Color picker HEX code: shows values like #2278C8 . Colour hex picker / hexadecimal color selector: same idea, with British spelling. Color wheel color picker / color wheel chooser: select by hue, saturation, and brightness. Color picker with RGB & HEX: shows both at the same time. Some tools also act as a color picker from image (or colour picker from photo ), where you upload a picture and click to read colors from it. 2.
