CanDoYa Accessible Palette Generator vs Paletto Studio

CanDoYa Accessible Palette Generator is a free web and browser-extension tool that turns a brand color and page background into interface color roles. It generates text, muted text, surface, primary, on-primary, accent, and border colors, then checks intended foreground/background pairs against WCAG contrast thresholds. Users choose AA or AAA targets and receive exact ratios with pass or fail results. The generator keeps the chosen hue and saturation where possible, searching lighter or darker variants to meet the selected ratio. Accent colors may use analogous, complementary, or triadic hues and receive the same contrast check. A live interface preview shows the palette in context. Individual HEX values or a complete CSS custom-property block can be copied. Palette generation, contrast measurement, and CSS export run locally in the browser, and entered colors are not uploaded. The free plan allows unlimited palettes without an account or usage limit. Most tools continue working offline after the page loads. The report evaluates opaque sRGB contrast only and does not establish whole-product accessibility.

Paletto Studio is a free web-based color tool for surface pattern designers. It can extract colors from a photo, refine them with harmony tools, and preview them on a design in the browser. Users can also create palettes from pasted hex codes or colors in their library. The palette tool accepts PNG, JPG, and WEBP images up to 50MB. Recoloring can start from hex codes, a library palette, or a newly created one, and palettes can be exported for Photoshop, Procreate, and more. Palette and recolor tools work without an account. Signing in lets users save palettes, organize them into collections, and load them into the tools. Uploaded images are processed in the browser and are not sent to Paletto Studio’s servers or third parties. Users own their designs and palettes, but the terms do not guarantee that exported colors will match physical print output; monitor calibration and substrate variation can affect it.
