Another example of a web banner that I really like and think works, it advertises the event name very clearly and shows clearly also where the event is happening. The colors are an excellent choice and the blending in of the picture really works too.
In this design, I see the use of colour, type, shape. Colour - The use of the colours green and gold/yellow is used to enable to a patriot spirit within as the colour greens and gold are our national colours which defines us as a society. Also the uses of these colours within the design work really well together creating balance.
