When preparing presentation materials it is advisable to remember that you do not have to write down everything you want to say on the slides. Too much content in combination with a small font gives a restless impression and makes reading difficult. It is better to have more pages with less text than one slide crammed with information.
Powerpoint slides are made by using Kameleon templates. Typography is Times New Roman in titles and Arial in the body text. Primary Fortum light green never smaller than 36 pt in title.
Use primary colours and complementary colours in graphs.
