Free Professional Color Picker — HEX, RGB, HSL, CMYK, Flutter, Tailwind & WCAG
SuccessMate's Color Picker Pro is the most complete free color tool for web developers, UI/UX designers, Flutter developers, and graphic designers across India, the USA, UK, Canada, Australia, Germany, and the UAE. Pick any color and instantly get values in every major format — HEX for CSS, RGB for web and print, HSL for CSS variables, CMYK for print design, Flutter Color() for Dart apps, Color() for Android XML, and Color() for SwiftUI — all in one place with one-click copy.
Web accessibility is now legally required in many countries. Our built-in WCAG 2.1 contrast checker instantly shows whether your color passes AA (4.5:1) and AAA (7:1) contrast ratios against white and black backgrounds — saving hours of manual testing. Tailwind CSS developers can copy the exact CSS variable or config value. Flutter and Android developers in India get the exact color format for their codebase with zero conversion needed.
The Tailwind-style shade generator creates 11 steps from 50 to 950 — just like a professional design system. Color harmony palettes (Complementary, Analogous, Triadic, Tetradic) help designers create professional color schemes using color theory. Upload any image — product photo, logo, screenshot — to extract its exact colors with a single click. Color history saves your last 12 picked colors for reference.

❓ Frequently Asked Questions
What is the Flutter Color format? ▾
Flutter uses Color(0xFFRRGGBB) where FF is full opacity and RRGGBB is the hex value. For example #FF6B00 becomes Color(0xFFFF6B00). This tool generates the exact Flutter/Dart code instantly.
What is WCAG contrast ratio and why does it matter? ▾
WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios for readable text. AA requires 4.5:1 for normal text, AAA requires 7:1. Most countries now legally require websites to meet at least WCAG AA. Our checker shows pass/fail instantly.
What is the difference between HEX, RGB, HSL, and CMYK? ▾
HEX (#FF6B00) is used in HTML/CSS. RGB shows red/green/blue values (0-255) — used in CSS and digital screens. HSL (hue/saturation/lightness) is more intuitive for design. CMYK is used for print design and professional printing workflows.
How do I extract colors from an image? ▾
Click "Upload Image" in the Extract Colors section. Your image appears on a canvas — click anywhere on it to pick the exact pixel color at that point. All extracted colors appear as swatches you can click to load into the picker.
What are color harmonies? ▾
Color harmonies are scientifically balanced color combinations based on the color wheel. Complementary uses opposite colors for high contrast. Analogous uses adjacent colors for harmony. Triadic uses 3 equally-spaced colors. Tetradic uses 4 colors at 90° intervals for rich schemes.
