About Color Tools
The color picker and converter on useTool handles the most common color workflow in design and development: identifying a color from a visual source and converting it between the formats used in different tools and contexts. HEX codes are the standard for web CSS and most design tools. RGB values are used in image editing software, CSS, and some APIs. HSL (hue, saturation, lightness) is more intuitive for adjusting colors programmatically — changing lightness while keeping hue constant, for example.
The picker lets you click any pixel on a loaded image to extract its exact color value, which is useful for matching colors from screenshots, brand assets, or reference designs when the source file isn't available. Conversion between all three color formats happens instantly. The tool runs entirely in your browser — no image data is uploaded or stored anywhere.
