Architects for Amazon.com have submitted updated drawings for the company’s proposed campus on the edge of downtown Seattle — showing for the first time how the company wants to use colorful exteriors to make its new towers stand out against the city’s skyline and (let’s face it) frequently gray skies.

The plans show the towers and adjacent buildings accented with colors including including green, red and yellow, with panels and fins giving the buildings different appearances depending on the angles from which they’re viewed.

Amazon’s proposed campus would have three 37-story office towers and related buildings, connected via streetcar to the company’s existing buildings in South Lake Union. Amazon’s architects from NBBJ have told city officials that the company’s is intent on “building a neighborhood, not a campus” — integrating its new project into the surrounding neighborhood.

The Seattle Times spotted the new drawings earlier today. See the full document here. Amazon’s update was submitted in advance of a Sept. 25 meeting of the Downtown Design Review Board. Click on any image below to open a gallery of pictures.
