HexTo

HexTo is a comprehensive, browser-based color toolkit built for designers, developers, and accessibility-focused creators. It combines essential color features into one streamlined interface, eliminating the need for multiple tools. With HexTo, you can convert between a wide range of color formats including HEX, RGB, HSL, HSB, and CMYK—all in real time. Its contrast checker ensures accessibility by calculating WCAG compliance and visually previewing contrast pass/fail states. This makes it ideal for building accessible UI components and websites. You can explore and generate color harmonies like monochromatic, analogous, complementary, triadic, split, and tetradic schemes, giving you creative flexibility when building design systems or themes. The integrated vision simulator lets you preview how your colors appear to users with different types of color blindness, such as protanopia or deuteranopia—helping you build more inclusive designs. HexTo also allows you to create, organize, and export custom color palettes. Export options include JSON (for developers) or image swatches (for presentations). Additionally, you can define and export design tokens with names and structure, making it easy to plug colors into any design system or codebase. All features are optimized for mobile and desktop, with a responsive layout and built-in dark mode. HexTo also stores recent color history locally for quick reuse and iteration. Whether you’re creating a brand palette, ensuring color accessibility, or prototyping a UI, HexTo is designed to be your all-in-one solution for working with color.
