Color-Card

Browse palettes, convert color spaces, save custom palettes, and unlock advanced Pro color generation in one tab.

Color-Card is a major product upgrade that keeps the original click-to-copy Material palette experience, while expanding it into a full color workflow tool for developers and designers. Version 1.x focused on a single Material Design palette. Version 2.0 keeps that fast workflow fully intact, but expands it into a much more capable tool for developers, designers, and presentation creators. What stays from the original version: - Full palette view in a spacious browser tab - One-click copy for color values - HEX / RGB switching - Optional "#" toggle for HEX copying What is new in the free version of 2.5: - Harmony page - Key Color input with HEX and HSL support - True HSL saturation/lightness picker - Four synchronized harmony wheels: - Accent / complementary color - Analogous colors - Triadic colors - Split-complementary colors - Click any Harmony swatch to copy the visible value - Harmony is available to Free and Pro users Pro features (in-app-purchase): - Auto Palette: generate tonal palettes from a seed color with multiple modes for general design, modern UI, high contrast, and data charts - Dynamic Color: extract a representative color from an uploaded image and generate Material-style tonal palettes and theme roles - Optional Google-account-based Pro verification for lifetime unlock Comparing with 1.x, Color-Card 2.0 is not just a version-number update. It is a major upgrade in functionality, interface design, and everyday usability, while preserving the simple click-to-copy experience that made the original version useful. Ideal for frontend developers, UI/UX designers, product designers, and anyone who frequently works with color values in websites, apps, dashboards, slides, or presentations.
