Scale is a free color scale generator designed to simplify the process of creating harmonious color ramps. Rather than manually selecting and adjusting colors by eye, Scale uses a generative method to produce systematic color scales from a base color or set of parameters. The tool helps designers and developers build consistent color systems for design tokens, UI themes, and data visualizations without requiring extensive manual fine-tuning.
Scale serves practical workflows across design and development. Use it to establish a complete color palette for a design system without manually testing dozens of color combinations. It works well for creating accessible color contrast ramps needed in modern UI kits, building data visualization color schemes for charts and dashboards, generating tonal variations for component states (hover, active, disabled), and exporting tokens for front-end implementation. Rather than guessing at saturation and lightness values, Scale automates the systematic progression between colors.
Scale is most useful for designers building design systems, UX professionals creating consistent color tokens, and developers implementing themeable interfaces. It benefits teams that need repeatable, mathematically-sound color scales rather than arbitrary selections. Product designers working with data visualization also find Scale helpful for generating perceptually balanced color schemes. Since Scale is free and web-based, it suits both independent designers and larger teams seeking a lightweight alternative to more complex color management systems. Visit Scale
