Coolors vs AllTools: Generation vs Extraction
Coolors and the AllTools Color Palette Extractor look similar at first glance — both give you color palettes. But they solve fundamentally different problems.
Coolors is a palette generator. Press the spacebar and it generates a random five-color palette using color theory algorithms. You can lock colors you like, adjust hue/saturation/brightness, and explore until you find a combination that works. It also has an image extraction feature, but its core strength is algorithmic palette creation.
The AllTools Color Palette Extractor is a palette extractor. It takes YOUR image — a photo, a logo, a screenshot, a painting — and pulls the actual dominant colors from it. No randomness, no generation. The colors come from the source material.
The distinction matters: generation gives you infinite possibilities but requires curation. Extraction gives you specific, grounded results tied to a real visual reference.
Quick Summary
Choose Coolors if: You don’t have a source image and want to explore random color combinations, need a spacebar-to-generate workflow for brainstorming, or want to fine-tune palettes with granular HSB adjustments.
Choose AllTools if: You have a specific image (photo, logo, screenshot) and need its exact colors as HEX/RGB/CSS values. You want privacy (no upload), semantic color roles, and flexible palette sizes.

How Image Extraction Compares
Both tools can extract colors from images, but the implementations differ significantly.
Coolors’ Image Extraction
Coolors has a “Create palette from photo” feature accessible from the toolbar. You upload an image to their servers, and Coolors returns a five-color palette. You can drag color pins on the image to adjust which areas are sampled.
The extraction is locked to five colors on the free plan. The results are decent but basic — you get five HEX values without any categorization or semantic mapping. Export options beyond basic copy require a Pro subscription at $3/month.
AllTools’ Image Extraction
The Color Palette Extractor processes your image entirely in the browser. No upload. The quantization runs in the OKLCH perceptual color space, which better represents how humans see color differences.
You choose the palette size: 4 for minimal, 8 for balanced, 12 for detailed, or any custom number. Beyond the quantized palette, AllTools generates semantic swatches (Vibrant, Muted, Dark Vibrant, Dark Muted, Light Vibrant, Light Muted) that map to common design system roles.
Export includes HEX, RGB, CSS variables, Tailwind config, and JSON — all free, no account.
Where Coolors Wins
Coolors is the better choice for:
- Palette generation from scratch — Coolors’ spacebar-to-generate workflow is unmatched for brainstorming. If you don’t have a reference image and just need color ideas, this is the fastest way to explore. AllTools doesn’t generate random palettes at all.
- Fine-tuning individual colors — Coolors lets you lock specific colors, then regenerate the rest. You can adjust hue, saturation, and brightness of each color individually. This iterative refinement is perfect for dialing in a palette.
- Saved collections — With a Coolors account, you can save unlimited palettes and organize them into collections. AllTools has no account system and no saved history.
- Community and trending palettes — Coolors’ Explore section shows popular palettes from other users. This social discovery is useful when you want inspiration without a source image.
- Color blindness simulator — Coolors includes a real-time simulator that shows how your palette appears to people with various forms of color vision deficiency. This is a valuable accessibility tool.
- Mobile app — Coolors has a polished iOS app for capturing palettes on the go, including from your phone’s camera. AllTools is web-only.
Where AllTools Wins
AllTools is the better choice for:
- Accurate image extraction — Color extraction is AllTools’ core feature, not an add-on. The OKLCH-based quantization produces more perceptually accurate results than Coolors’ RGB-based extraction. Colors that look dominant to the human eye actually rank as dominant.
- Privacy — Your image never leaves your browser. No upload, no server processing, no third-party storage. For confidential client work, brand assets, or personal photos, this is non-negotiable for many professionals.
- Flexible palette sizes — Coolors locks you to five colors. AllTools lets you extract 4, 6, 8, 12, or any custom number. Different projects need different levels of color detail.
- Semantic swatches — The Vibrant/Muted/Dark/Light categorization tells you which extracted color to use as your primary, background, text, or accent. Coolors gives you five unlabeled swatches.
- Developer exports for free — CSS variables, Tailwind config, and JSON export are free on AllTools. Coolors gates several export formats behind the Pro paywall.
- Offline capability — AllTools works without an internet connection after initial load. Coolors requires it for all features.
Different Tools for Different Stages
The best workflow often uses both tools at different stages of a project.
Starting from a reference image? Use AllTools. You have a mood board photo, a client’s logo, a screenshot of a competitor’s site, or a photograph that captures the mood you want. Extract the exact colors from that specific image.
Starting from nothing? Use Coolors. You have a blank canvas and need to explore color directions. Generate, lock, regenerate, refine until something clicks.
Starting from one color? Use Coolors. You know you want a specific blue but need four more colors that work with it. Lock the blue, generate companions.
Need CSS-ready output? Use AllTools. Copy the full palette as CSS custom properties or a Tailwind config object directly into your codebase. No Pro subscription needed.
Many designers extract a palette from a reference image with AllTools, then take those base colors into Coolors for fine-tuning and exploration. The tools complement each other.
The Privacy Factor
Coolors uploads your image to their servers for extraction. For stock photos and generic images, this is fine. For unreleased product designs, client confidential materials, or personal photos, sending images to a third-party server introduces risk that may violate NDAs or privacy policies.
AllTools eliminates this concern entirely. The image is decoded and analyzed in your browser’s memory. You can verify this by opening DevTools Network tab — zero bytes transmitted during extraction.
Try the Color Palette Extractor
Have a specific image you need colors from? Drop it into the Color Palette Extractor and get HEX, RGB, CSS variables, and semantic swatches in seconds. No account, no upload, no cost. Your image stays on your device.
Need random palette inspiration instead? Coolors is great for that. Use both tools for what they do best.
