If you want the umbrella to be used on a regular basis it is best to go with a sober design. Flashy umbrellas often stay in the boot when it rains. Compared to people from warmer climes, we Westerners still opt for discreet umbrellas. Does your company have a company colour? Then start from that main colour and combine it with logo colours. If you have a great image that symbolises your company or your professional activities then we can transfer it onto the fabric of your umbrella.
Other ideas can always be translated to an umbrella context.
