Most startups are making this UI mistake

Most UI problems are not layout problems.

They’re color hierarchy problems.

Too many products use:
❌ multiple accent colors
❌ harsh contrast
❌ visual noise
❌ inconsistent states

The result?

Interfaces that feel “busy” instead of premium.

The best products feel calm because every color has a purpose.

Curious:
What’s the biggest UI mistake you see modern startups making today?
