When the Color Palette Generator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The palette looks pretty but unusable
Run every text-background pair through the contrast checker before committing.
Colours are too similar to tell apart
Increase the spread - try a different harmony rule or shift the seed lightness.
I have no neutral colours
Palettes focus on hues - derive greys from your seed lightness for surfaces and text.
The scheme clashes with existing brand assets
Seed from the existing brand colour rather than an arbitrary starting point.
Regenerating changed everything
Lock the seed and regenerate only the accents you dislike.
I cannot copy values cleanly
Each swatch exposes its hex on click - copy individually into your variables file.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Trusting harmony rules to guarantee contrast
- Generating dozens of palettes without choosing
- Ignoring that UI needs neutrals too
- Picking a palette that fails accessibility checks
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
What does harmony mean here?
It positions colours at proven relationships on the colour wheel - opposite, side by side, or evenly spaced.
Can I edit the generated colours?
Yes - regenerate or adjust the seed; every output is a value you can tweak manually.
Are the palettes accessible?
Harmony is aesthetic, not a11y - always verify pairs with the contrast checker.
Is anything uploaded?
No - generation happens entirely in your browser.
