Why is Blue a Popular Color in UI Design?

When you think blue brands, what comes to mind?

That’s right, a bunch of names!

Facebook, LinkedIn, Twitter, Skype, Yahoo!, WordPress, Samsung, Nokia, Intel, PayPal, and many, many more have blue logos and UIs.

So why is blue such a popular color in UI design?

Well, there are mainly two types of reasons behind blue’s popularity in UI design: psychological reasons, and accessibility reasons.

Psychological Reasons

A studyfound that blue is the favorite color of college students.

Another study found that in many countries, blue is the people’s most favorite color, across genders and age groups, probably because it invokes blue skies and peaceful lakes, and therefore serenity.

Indeed, blue can have a calming effect on people,as studies showed that installing blue lights in the streets helped decrease crime, and installing them in train stations helped decrease suicide rates.

Blue can arguably encourage intellectual activity,reason, and logical thought, but it can also have a soothing effect and lower blood pressure.

Generally speaking, blue is reputed in the design community for being associated with safety, innovation, stability, and trustworthiness.

All these positive psychological effects are some of the reasons why blue is so coveted in UI design.

Other reasons are accessibility.

Accessibility and Inclusiveness

To design an accessible UI, one has to think about people with color blindness.

Don’t be fooled by the name though, having color blindness does not mean that the person has some form of blindness. It just means that theysee color differently.

Color blindness is an an inherited condition that affects men more than women.

The most common type of color blindnessis the red-green color blindness, whereas the blue-yellow color blindness is rarer.

This is why designers opt for blue, as many people with poor color discrimination can still see it.

Did you know that Facebook’s UI is blue because Mark Zuckerberg is red-green colorblind?

Mark revealed his color blindness in an interview with the New Yorker,where he said: “blue is the richest color for me—I can see all of blue.”

To Blue or Not to Blue?

With all these good reasons to use blue in UI design, this does not mean that everybody must use it.

Otherwise, we will end up creating a sea of blue logos and brands where it would be difficult to stand out and catch the attention of users and customers.

However, many designs can use blue and still look fresh and distinctive, thanks to the magic power or color and to the use of color variations.

Whatever colors you choose, remember that prototyping and testing are key to determining their suitability for your audience.

Remember also that your color palette is a key factor that affects not only user loyalty but also conversions–color is key for marketingas well.

So, what is your favorite color for UI design and why?
