iOS7 - Calculator Colours

after making my own version of the iOS7 calculator i got asked by Robin Schelvis who found me through Facebook and needed some help on a Uni Project. He asked if i could make colour variants of my calculator design for the iPhone 5C so that he can use.

After some free time i mocked this up and made 5 different colour schemes to match the 5C. Robin will be making his own version with the colours i have given him and use the initial design i created as a base for his project.

attached is all colours in real pixels :)
