Coloured A4 Paper
There's not enough colour in the office supplies world. Let's rectify that by slipping colourful sheets of A4 paper into our reports and handouts. Keep your audience guessing: “I wonder what colour paper she's used to present the Q2 projections?”
Use coloured A4 paper to disseminate passion to your audience. Different colours are strongly associated with certain emotions. You may well be aware that blue is associated with coolness and calm, but did you know that violet can convey introversion, sometimes even decadence?
