Magazine Covers - Do they stand out on the shelf?

I have tried to show some of the more eye catching cover designs that I have found to show what I am competing against on the shelves. The majority advertise the contents on the magazine cover to further inform and entice the customers to buy their copy. The luxurious style I wish to portray in my magazine range will have to be evident throughout. This will be produced using types of stock, perforations and different stock.

Because the magazines use a lot of colour to entice customers, I thought the best way to stand out on the shelf is to use one colour. It will really stand out against the rest of the type and image bombarding the audience, and will be a clean change and a chance for the customer to rest their eyes on a plain and clear WHITE cover.
