Target audience research #2

How will I make my magazine appeal to my ideal target audience (females of any age)? Well, If I make the cover similar to a cosmopolitan or seventeen it will mainly catch younger readers, and if I make the cover similar to an instyle magazine, I will mainly catch an older audience, if I make a cover similar to vogues, I will mainly catch the attention of people with higher incomes. None of this options appeal me, so I’ll use a combination of all these magazines, making my orignal magazine, trying to make it appealing to all the different girls! I will use bold, yet neutral colors such as red, black, white, dark blue, dark green, etc.
