ColorBox vs ihatecolors Image Extractor

ColorBox is a free web tool and extension for creating color systems and accessible palettes. You can adjust multiple colors in one tab and share a system as a URL or JSON file. Contrast indicators show 3:1, 4.5:1, and 7:1 levels for color sets, while HSV and OKLCH provide color-space modes. Auto Dark Mode creates an inverted set from original inputs; duplicated sets can also be edited manually. Hue progression rotates clockwise or counterclockwise. Export options include Config, Output, Tailwind, CSS, OKLCH, and Swift. The maker describes importing systems into Figma through a plugin and JSON, with custom step names and generated Paint Styles. A Sketch route uses that Figma workflow, then SVG export. The color algorithm can be consumed through NPM with exported JSON for code generation. Custom curves were described as unavailable in ColorBox at the cited time. The free plan is ad-free.

ihatecolors Image Extractor is a free web tool that analyzes an uploaded mockup or screenshot, finds four dominant colors, assigns interface roles, and checks contrast. It accepts PNG, JPG, WebP and SVG files. Colors are sampled on a canvas and clustered to identify the most prominent shades, then mapped to Background, Primary Accent, Secondary and Body Text. You can copy generated CSS variables or a Tailwind CSS configuration. Live previews show the palette in landing, blog and dashboard mockups. Its accessibility feature describes a WCAG 2.1 contrast check and sorts colors by luminance to identify a background and text combination. The site says its algorithms run client-side. No account is required; saved favourites stay in browser localStorage. The free plan is available for personal and commercial projects. The FAQ cautions that the check does not guarantee an accessible palette.
