“Reject” is harder to see than “Accept”

Can the reject button on a cookie banner be smaller or greyed out?

Short answer

It shouldn’t be. A small grey “Reject” next to a big coloured “Accept” pushes people to accept. EU and California rules treat this as a dark pattern. Give both buttons the same size, weight and contrast.

Why it matters

Visual nudging toward “Accept” is a recognised deceptive design pattern and weakens the validity of the consent you collect.

How to fix it

  1. Style accept and reject identically: same component, size and contrast.
  2. Avoid pre-focusing or animating only the accept button.
Steps for OneTrust

  3. Use Button layout to put it next to Accept, and give it the same look.
  4. Republish the script.
