Here are some initial colour swatch variations I created. This is a net of a basic airplane that would be used for one of our designs. I have kept the design simple therefore it is easy to construct the plane and understand where the fold should be. I have used consistent imagery to create a powerful theme throughout the designs, changing colours to experiment with different visual solutions.
After resolving various colour themes I decided that yellow was really powerful and so I went back and experimented with different colour themes in earlier stages of my design to see the outcome.
