Design tools on ToolzPedia give developers, designers, and content creators precise control over colour and visual style without needing a desktop application. Colour is one of the most fundamental elements of visual design, and working with it precisely requires the ability to move fluently between colour spaces: HEX values are used in CSS and HTML, RGB values are used in code and image editing, HSL values make it intuitive to adjust lightness and saturation while keeping a hue consistent, and CMYK values are needed for print production. The ToolzPedia colour picker supports all four formats with live two-way conversion, a visual canvas picker, and a hue/saturation/lightness slider set. The gradient generator produces CSS-ready linear and radial gradient code with adjustable stops, angles, and colour positions. Both tools are built with web developers as the primary audience: the output is always clean, copy-paste-ready CSS or HEX values with no unnecessary formatting. All processing runs in the browser with no data transmitted.
