When I first learned about what a "style tile" was, I fell in love with the idea for working out branding concepts. I created this format for our company, Demand by Design, and have used it successfully for a few companies now who really like this presentation. I'm eventually going to post some others so you can see how flexible this layout is, and how it can also include photography style, samples, adjectives, etc.
This is finally one that I've done for a company that we're trying to start at Demand by Design. The first image is a few stabs at color and placement, and the second one was the second round after we'd narrowed down which ones we liked. I'll be tightening up the logo and finding more alignments once we settle on a final version.
