If you’re Instagram-obsessed, prepare for your phone screen to look drastically different when you update your apps. Facebook on Wednesday released a redesigned logo of Instagram as well as creative apps Layout, Boomerang and Hyperlapse.

Instagram also redesigned the inside of the app. The change eliminates the blue and black color of the top and bottom bar and instead makes it light gray and white. The way the app works has not been altered, however.

Why the new look? “Frankly, we thought we could make it better,” Ian Spalter, Instagram head of design, told WWD.

Instagram launched in 2010 as a simple photo-sharing app on mobile. Facebook acquired the company in April 2012 for $1 billion when the app had already garnered 100 million active users.

The redesign is a reflection of the community, according to a video about the change. “Our updated look reflects how vibrant and diverse your storytelling has become,” Instagram's blog post about the update reads.

Instagram has garnered more than 400 million monthly active users. More than 80 million photos and videos are shared every day, according to the blog post.

Wednesday’s redesign is the fourth major logo change for the app. The previous three were designed by Instagram founder Kevin Systrom, according to WWD. “Inspired by the previous app icon, the new one represents a simpler camera and the rainbow lives on in gradient form,” the blog post reads.

The new look brings more simplicity to the popular app, said Howard Belk, co-CEO and chief creative officer for global branding firm Siegel+Gale. "They’ve kept the essentials — the camera, the color gradation— yet reinterpreted them in a completely intuitive way. I’m sure some sentimentalists will rail at the loss of the cute camera and the Polaroid spectrum, but I expect the community will very quickly move on," Belk wrote in an email.

While Wednesday's update is an aesthetic change both outside and inside the app, the functionality of Instagram also has been drastically altered over the past year. Yesterday, Facebook added dynamic ads to Instagram, which means advertisers can upload their entire product catalog to the app and target specific items to users based on their browsing history.

Facebook also applied an algorithm to Instagram in March. Before that, the app had displayed photos and videos chronologically.

Still, despite the changes, the app is expected to bring in high revenues for Facebook this year. Instagram will draw at least $3.2 billion in 2016, a Credit Suisse report estimated. The app introduced advertising in September.
