ColorKit vs ColorPalette Pro

ColorKit is a free web toolkit for designers and artists working with color palettes, gradients, and other design elements. Its palette generator offers AI prompts, style modes, color locking, and controls for hue, brightness, saturation, and temperature. Palettes can be exported as PNG, copied as CSV or an array, or shared by URL. The image palette tool extracts 2 to 10 colors, allows manual adjustment of color points, and can create a PNG collage; ColorKit says images used by this tool are never uploaded to its server. The gradient maker supports linear, radial, and conic gradients, adjustable color stops, AI generation, CSS copying, and image or code export, with up to eight stops per gradient. A contrast checker calculates text and background contrast ratios and can pick colors from an uploaded image or image URL. Other listed tools include a color picker, shade generator, SVG color changer, background maker, and color mixer. ColorKit is available on the web. Image palette extraction needs no signup; a free account is required to save palettes and gradients.

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.
