We are going for a bright, fun, welcoming design. Salsa is artful, upbeat and energetic, and we want to communicate that through the design via warm, vibrant colors and an organic design.
A literal or abstract representation of two people dancing can work but is by no means required. In fact, we'd love to see the lettering creatively incorporated in the logo. That being said, it should be obvious at a glance that the logo is for a platform related to dance, whether it be via creative lettering or a depiction of dancing accompanying the lettering.
I find simplistic, elegant designs to be very attractive. Keep in mind that this will be a product for iphone and android devices, so a logo that can translate well into a small screen or eventually into an app icon is best.
Eventually, this logo will be printed on t-shirts, seen in an app on mobile devices, be viewed on webpages, and on facebook. In the future, an app icon will be created to match this logo.
