ColorPalette Pro vs Paletto Studio

ColorPalette Pro is a web app for generating customizable color palettes from a base color. It creates analogous, complementary, split complementary, triadic, tetradic, and tint-and-shade palettes, with square, triangle, circle, and diamond variations for each type. Colors can be entered as text, adjusted with sliders, selected with an eyedropper, recalled from history, chosen at random, or supplied through a URL. Supported color spaces include OKLCH, LAB, LCH, HSL, and RGB. UI mode generates interface palettes with surface and on-surface colors, including light and dark versions. Palette values can be copied as CSS, saved as a CSS file, or rendered as an image; a URL can preserve the chosen color and most options for sharing. Palette images can be dragged into Figma for sampling. The app matches color names through an API using hex values and uses Color.js for color-science functions. It is open source under the MIT license, and its maker says there are no plans for ads or subscriptions. The eyedropper is unavailable in Firefox and mobile browsers.

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.
