As a designer or developer, you probably spend more time than you’d like to admit switching between color tools. One tab for generating palettes, another for checking contrast ratios, a third for converting HEX to RGB, and maybe a fourth for extracting colors from images.
It’s tedious. And most of these tools require sign-ups, have annoying ads, or upload your images to their servers.
That’s why I want to share HueGrad — a free color tool station that bundles six essential color tools into one clean interface. No sign-up, no uploads, no limits. Everything runs 100% in your browser.
Here’s a walkthrough of each tool and how to use it.

- 🎨 Palette Generator The palette generator lets you create color schemes based on color theory principles. Choose from six harmony types:
Monochromatic — variations of a single hue
Complementary — two colors opposite on the wheel
Triadic — three evenly spaced colors
Tetradic — four colors forming a rectangle
Analogous — colors next to each other on the wheel
Split Complementary — a base color plus two adjacent to its complement
Pro tip: Press the Space key to instantly generate a new random palette. Click any color to copy its HEX code. Lock colors you like with the 🔒 button to keep them while regenerating the rest.
This alone replaces Coolors for most quick palette tasks. But unlike Coolors, you also get Tailwind color name matching — so you can find the closest Tailwind color for any swatch you generate.
- 🔄 Color Converter Ever needed to convert a HEX color to RGB, HSL, CMYK, or HSV? Instead of Googling “hex to rgb converter” every time (we’ve all done it), this tool gives you all formats instantly.
Just type or paste any color value, and it converts across all five formats in real-time. Copy any format with a single click.
Write on Medium
It’s the kind of tool that seems simple but saves you minutes every day if you work with CSS, design specs, or print production.
- 🌈 Gradient Generator Creating CSS gradients can be fiddly. The gradient generator lets you visually build three types of gradients:
Linear gradients — with adjustable angle
Radial gradients — for circular color transitions
Conic gradients — for pie-chart-style color sweeps
Add as many color stops as you need, drag to reposition them, and copy the generated CSS code with one click. There’s also a preset library with 15 ready-to-use gradient combinations if you need inspiration.
- 📷 Image Color Extractor Upload any image and the tool extracts the dominant colors automatically. This is perfect for:
Creating a color palette from a brand photo
Matching your UI colors to a hero image
Analyzing the color scheme of a competitor’s screenshot

Privacy note: The image never leaves your browser. All processing happens locally using the Canvas API — no upload, no server, no tracking.
- 👠WCAG Contrast Checker Accessibility isn’t optional anymore. The contrast checker evaluates your foreground/background color pairs against WCAG 2.1 standards:
AA — requires 4.5:1 for normal text, 3:1 for large text
AAA — requires 7:1 for normal text, 4.5:1 for large text
Enter your two colors and instantly see if they pass or fail, along with the exact contrast ratio. This is essential for anyone building accessible web interfaces.
- 🔠Color Blindness Simulator This is the tool that most color platforms don’t include. It simulates how your color palette appears to users with:
Protanopia — red-blind
Deuteranopia — green-blind
Tritanopia — blue-blind
About 1 in 12 men and 1 in 200 women have some form of color vision deficiency. If you’re designing for a broad audience, you need to know how your colors look to everyone. This simulator makes it effortless to check.
Why I Like HueGrad
There are plenty of individual color tools out there — Coolors, Adobe Color, Khroma, Color Hunt. Each is good at what it does. But HueGrad stands out for a few reasons:
All-in-one. Six tools in one tab. No more juggling bookmarks.
Privacy-first. Nothing is uploaded. No account needed. No tracking. Your images and color data stay in your browser.
No friction. No sign-up wall, no “upgrade to pro” prompts, no daily limits. You open the site and start working.
Keyboard-friendly. Press Space to generate palettes. Click to copy. It feels fast and responsive.
Built for developers too. CSS code export, Tailwind matching, HEX/RGB/HSL/CMYK/HSV conversion — it speaks developer.
How to Get Started
Just open huegrad.com in your browser. No download, no installation, no account. Pick a tool from the tab bar and start working.
If you found this helpful, share it with a designer or developer who juggles too many color tool tabs. And if you have feature requests, I’d love to hear them.
