The pros don't make those big bucks for nothing. Professional graphic designers put a lot of forethought into their design and color decisions. And many of the deciding factors are not artistic, but technical. One of the technical tips we picked up from Eric Scott, a graphic designer in Santa Monica, California, is to keep a logo's colors flexible so you can use it in a variety of ways.
Logos cost a lot of money to have designed.
By anticipating that you may use yours in a variety of ways, you can keep the color scheme flexible enough so one logo can always do the trick, thus saving money. If the logo's going to be used on the web or on TV, I have very different considerations than if it will be used solely in print. Eric tries to design his logos to have flexibility, sometimes not even committing to a single color scheme. I found it necessary to address issues of color every time the logo was to be used. The goal has always been to convey a handmade, and therefore personalized, quality with both the business identity and the individual packaging.
