5 Best Color Palette Generators in 2026 (Tested)

There are dozens of palette generators and most of them do the same thing slightly differently. I have spent more time than I should testing them, partly because I was building one myself and wanted to understand the field. Here is where each tool actually shines and where it does not.

1. Coolors

The one everyone starts with, and for good reason.

Hit spacebar, get five colors. Lock the ones you like, shuffle the rest. The loop is addictive and fast. You can go from nothing to a palette you are happy with in under a minute. Coolors built the spacebar mechanic and they still do it best.

Beyond the generator, the ecosystem is massive. Figma plugin, Adobe extension, iOS app, Chrome extension. Image-to-palette extraction. A community library with millions of saved palettes. Palette visualization on mockups. If your workflow is "I need colors for a brand deck by end of day," Coolors is the fastest route.

What it does not do: gradients. Every palette is flat swatches. You get hex codes, and what you do with them after is up to you. No image export, no video, no code beyond color values. The Pro plan ($3/mo) removes ads, unlocks 10-color palettes, and gives you unlimited collections.

Best for: quick ideation, teams that need a shared palette library, anyone in the Adobe/Figma ecosystem.

2. Adobe Color

The color wheel that has been around forever, and it is still good.

Adobe Color works differently from most generators. Instead of random shuffling, you pick a harmony rule (complementary, analogous, triadic, split-complementary) and drag points on a color wheel. The palette updates in real time as you move. It feels more like sculpting than slot-machining.

The killer feature is Creative Cloud sync. Save a palette and it appears in Photoshop, Illustrator, InDesign, and XD automatically. If you already live in Adobe, nothing else comes close to that integration. The accessibility tools are solid too: contrast ratios update in real time as you adjust colors.

What it does not do: the spacebar loop. There is no "surprise me" button that generates dozens of options quickly. The community palette library exists but it is harder to browse than Coolors. No gradient preview, no export as images.

Best for: designers in the Adobe ecosystem, projects where color theory precision matters more than speed.

3. Khroma

The AI-powered outlier.

Khroma asks you to pick 50 colors you like, then trains a neural network on your preferences. After that, it generates infinite palettes tuned to your taste. You can view them as typography, posters, gradients, or custom images.

The personalization is genuinely interesting. After the training step, the palettes feel less random than a spacebar generator. If you have a strong aesthetic but struggle to articulate it in hex codes, Khroma translates taste into palettes better than anything else I have tried.

What it does not do: the training step is a real commitment. You cannot skip it, and if your taste is broad, the results can feel narrow. No community, no export beyond copying values, no integrations, no API. The tool has not changed much in years, which is either a sign of maturity or abandonment depending on your perspective.

Best for: creative directors and brand designers who want AI that learns their style, not just random generation.

4. Realtime Colors

The one built specifically for web designers.

Realtime Colors does one thing no other generator does: it previews your palette on an actual website layout in real time. Pick a text color, background, primary, secondary, and accent, and watch them distribute across a real page with headers, buttons, cards, and body text. You immediately see if your palette works in context.

The contrast checker is built in and shows AA/AAA compliance for every combination. Export as CSS, SCSS, or a downloadable zip. Clean, focused, free.

What it does not do: random generation. You are building a palette manually, color by color, which is slower than spacebar generators. No community, no image export, no mobile app. It solves one specific problem (will this palette look good on a website?) and does not try to be anything else.

Best for: web developers and UI designers who want to see their palette in a real layout before committing.

5. InstantGradient

Full disclosure: I built this one. But the reason I built it is the gap I kept running into with every tool above.

Coolors gives you five hex codes. Adobe Color gives you a wheel. Khroma gives you AI suggestions. They all stop at the same place: flat swatches. You get colors, and then you have to go somewhere else to see what those colors actually look like as a gradient, a background, a visual asset.

InstantGradient renders every palette as a live animated mesh gradient using WebGL shaders. Same spacebar mechanic as Coolors, same harmonic generation (analogous, complementary, triadic, split). But while you work, you see the palette blending in real time. Some palettes that look great as swatches wash out as gradients. Others that seem boring in a strip come alive once the colors start moving.

Open

From there you can export as 4K PNG or WebP, animated MP4 video (up to 30 seconds), CSS, Tailwind v4, React, Vanilla JS, or JSON. Apply visual effects like fluted glass, grain, or distortion. Save to a library, build collections, share a public profile. Browse 4,900+ named color pages with conversions, contrast checking, and code snippets.

And if you are a developer: there is a REST API that lets you generate palettes, look up colors, and browse community data from your own code. None of the other tools on this list ship anything like it. API docs here.

What it does not do: Figma or Adobe plugins (yet). No mobile app. The community is smaller than Coolors (they have a decade head start). The CSS export is an approximation since mesh gradients cannot be reproduced with native CSS.

Pricing: free (5 saves, standard export). Pro $5/mo or $39/yr (unlimited saves, 4K, video, effects, code exports, API).

Best for: anyone who needs the palette as an actual visual asset, not just hex codes. And developers who want programmatic palette generation.

Which one should you use?

Depends on what you need:

Quick palette for a brand deck: Coolors. Nothing beats the speed.
Precise harmony rules + Adobe workflow: Adobe Color.
AI that learns your taste: Khroma.
Preview on a real website layout: Realtime Colors.
Palette as a gradient, image, video, or code: InstantGradient.

Most designers I talk to use two or three of these. They are not competitors as much as they are different tools for different moments in the design process.
