Representation on Cover

 Magazines have to cater to a large audience therefor they to target their audience and represent what the audience will find interesting. Here are some pointers I gathered about Representation on Cover of tech magazines

Blue light is associated with holograms and green light is associated night vision and therefor is greatly used tech magazines.

 Many prominent people like Elon Musk are used in the cover to attract a larger audience by adding the celebrity factor; a certain celebrity who many people look up to in their field

Some tech magazines are kept simple with only information on the cover

Some use scale models or something sensational like rocket on their cover. Gadgets are commonly advertised on the covers
