ACO vs CSS: Adobe Photoshop Color Swatches vs Web Design Tokens
Compare Adobe Photoshop binary ACO color palettes with modern CSS custom property variables and design tokens. Understand color spaces, naming, and frontend integration.
Adobe Color Swatch (.aco) is a proprietary binary palette format used in Photoshop and Creative Cloud to store named colors across sRGB, HSB, CMYK, and Lab color spaces. CSS Custom Properties (:root variables) and Tailwind tokens are modern web standards that allow dynamic theme styling, live dark-mode toggling, and instant UI implementation in frontend applications.
