One “Unbelievable” Call-to-Action Color Makes $80 Million
The $80 million color is: #0044CC
That “code” is a precise shade of blue, and it works when a link is the call-to-action.
When Microsoft was designing what would eventually become Bing, it tested a vast number of colors and it turned out that the one that users engaged with the most was indeed blue. More specifically, it was a shade of blue quite similar to the one used by Google.
Paul Ray, a user experience manager for Bing said on Tuesday that choosing that specific blue (#0044CC for you color enthusiasts) over some other hues amounted to an additional $80 million in annual revenue, when one factors in the additional clicks on advertisements and increased user engagement.

Now, many times you’ll use a link as a call to action. This one shade of blue is the color for links. Keep it underlined. Don’t be fancy. Don’t mix it up with other colors either.
What’s the perfect color for buttons?
Orange, or a shade of it. Typically this color contrasts the best with websites. The color of your button is ‘set apart’ from your website. There are tests that have proven this countless times. Here’s a few posts:
- Split Testing with a Genetic Algorithm
- How to Call to Action (their explanation of why orange works best)
- The attack of red [actually, orange] buttons: how GSM.nl reduced bounce rate by doing a simple change
If you go to Bing’s homepage, you’ll notice they use an orange search button. It is likely that they also found that orange is best for buttons.
This is the power of testing. Use the above shade of blue for links. And, for buttons, it needs to contrast with the rest of the site — this color is typically orange.

I’ve got to admit, I’ve come to the same basic conclusions on my own after years of testing (not that exact shade, but orange for buttons and blue for links). Interestingly enough, on display ads we’ve found that green eyes also result in a higher CTR…go figure.
Thanks for this post! I am going to use that color all the time in my banners now
It’s not surprising that blue sells as this also been known in the offline markting world. Interesting to note that orange works well for buttons.

Nice info. I’ve found myself wondering this every time I’ve created a landing page over the past 11 years. I split test and I’ve come to the same conclusions, but I never knew the exact color code.
Thanks!
Take that #0000FF!
And I’m reading this on a page where there’s no any blue link
@David: Haha yeah, I have get off of this free WP template one of these days. But, I prioritize landing pages.

Cool, good to know i def need to change my link color
Might give this color a try on my site.
The standard color for links have always been blue. No surprise but interesting to have stats added to backup the claims.
Maybe we need to plan for the next set of colors cause I’m sure these two color will get abused now to the point where it won’t be anymore good.
None-the-less, good post though.
@Dustin: Actually, the more websites that use this color, the more users will get used to clicking this color too–which is good.
Awesome. Will start testing the blue text and orange button. Complimentary colors! I knew I learned something from grade school. lol
Thanks for the post!
