Common Issues

A tool is not working or showing an error

Try these steps in order:

  1. Refresh the page (Ctrl/Cmd + R)
  2. Clear your browser's cache for omnicolor.pages.dev
  3. Try a different browser (Chrome, Firefox, Safari, Edge)
  4. Disable browser extensions that might block scripts
  5. Check that JavaScript is enabled

If the issue persists, please report a bug with details about your browser and the specific tool.

Copy buttons are not working

Copy functionality requires the Clipboard API, which needs a secure context (HTTPS) and browser permission. If copying fails:

  • Make sure the URL begins with https://
  • Check that your browser allows clipboard access to this site
  • Try selecting the value manually and using Ctrl/Cmd + C
Image upload is failing

Image uploads are limited to:

  • File types: JPG, PNG, WebP
  • File size: 10MB maximum
  • Image dimensions: 5000x5000 pixels maximum

If your image is within limits and still fails, the file may be corrupt — try re-saving it in an image editor.

Saved colors disappeared between sessions

Saved colors are stored in your browser's localStorage. They can disappear if:

  • You cleared your browser's site data
  • You switched browsers (localStorage is per-browser)
  • You are in private/incognito mode
  • Your browser is blocking storage for this site

To export your colors before clearing storage, use the Palette Exporter.

The site is slow on my device

OmniColor is designed to be fast, but performance can degrade on older devices or slow connections. If the site feels slow:

  • Use a modern browser (Chrome 90+, Safari 14+, Firefox 90+)
  • Close unnecessary browser tabs
  • Disable heavy browser extensions
  • Use an ad blocker to reduce third-party scripts
