What color should my CTA button be?

Whatever color contrasts most with the rest of your page. There is no universally best CTA color — "orange converts better" is a myth. The variable that matters is contrast: pick a color that does not appear elsewhere on the page so the CTA is visually unmissable. Test the same offer with two different high-contrast colors before committing.

Why "the best CTA color" is a meaningless question

The famous "red CTAs converted 21% better" study from HubSpot was on one page. Nielsen Norman Group has documented the same color winning and losing across hundreds of tests. The variable that consistently moves conversion is contrast, not hue. A green CTA on a green-themed site disappears; the same green on a neutral site pops.

The color-reservation rule

Pick one accent color and use it only for primary CTAs. If your hero subtitle uses the same color as your CTA, you've taught the visitor that the color isn't actionable. The most disciplined examples (Stripe's purple, Linear's purple, Notion's blue) reserve the brand accent strictly for things visitors should click — buttons, primary links, and nothing else.

How to actually pick

Sample three candidate colors — your brand accent, a high-contrast complement, and pure white or black depending on background — and run a 5-second test asking "where would you click?" The fastest-recognized color wins. Analyze your CTA for contrast issues you may have missed.

How many CTAs should be on a landing page?

One primary CTA repeated 2–4 times down the page (above the fold, after social proof, after objections, in the footer). The same offer, the same copy, the same color. Multiple competing primary CTAs reduce conversion by introducing decision fatigue. Secondary CTAs ("see pricing", "watch demo") are fine if visually subordinate to the primary.

What makes a good landing page CTA?

A high-converting CTA names the specific outcome the visitor receives, uses high-contrast color reserved exclusively for CTAs, sits above the fold without competing primary buttons, and includes friction-reducing microcopy underneath ("Free · No signup · 30 seconds"). Outcome-led copy beats action verbs by 30–40% in our analysis.

What makes a landing page effective?

An effective landing page does six things at once: states the outcome clearly in the headline, uses a single primary CTA, provides three or more concrete trust signals above the fold, loads in under 2.5 seconds, addresses the visitor's specific objection, and matches the message of the traffic source. Most pages do one or two well; the top 5% do all six.
