Logo Design Brief
We need a logo for the newly created "dieseltrbo.com" online magazine. The magazine will be targeting mine planners, engineers, and equipment manufacturers but with a more playful approach than traditional media for this group. The website will have lots of graphical content and will resemble online magazines such as "fast company.com" and "wired.com".
We require that the logo be modern and recognizable and entirely new. Needs to be red and black. The final design should be playful and professional and will ideally be bold enough to appeal to a predominantly male audience.
Final submission must include vector version of the logo, high resolution .jpg and high resolution .png.
Updates
Some updates were made to design brief which include submission requirements. I have at least three designs that I like but they need a pictorial to make them a more complete package.
Thanks for your efforts.
DieselTrbo Team.
