Market research

I would like to use a black and white image for my front cover. Therefore i have been researching successful music magazines that use black and white images. This is to see how they work and how to make them look good. I found a successful magazine, with the same colour scheme i am planning to do. I also found another one with different colours. I like the idea of having a black and white image because the writing stands out more than on a coloured background. To make my cover look good i think the trick is to make the colours very bright. Also to have a limited colour scheme to keep the simple look, as if there were lots of colours used, the writing would look too busy and the image would be over powered. Also i need to think about what cover lines are what colours because white will not stand out very well on light or grey areas.
