1. These are some t-shirt designs for energy drink products. All of the designs are
very basic, but very appealing to the fans of the energy drink. Rockstar’s
design goes well as the colours contrast well on black material. Any t-shirt that
comes out will have an appeal to fans as they want to get their hands on any
merchandise possible.
Monster Energy’s design also contrasts well with the colours used and any fans
will be happy enough to promote their favourite energy drink by wearing their
t-shirts. Shark’s design is slightly different as the colours used contrast oddly,
as it seems that the majority of energy drink t-shirt design you see do not
normally use white material with the design on top. However, it still works out
as the colours of the logo stand out. Again, any fans will also be happy to
promote their favourite energy drinks.
