PowerPoint Design Brief
We need a new PowerPoint template that gives us a fresh modern look and feel without a complete re-brand. We do not want to change our logo or colour scheme however want would like to use them in a different way. Currently our template uses a lot of block colour and we would like to utilise more white with our colour scheme acting as accent colours.
I tried to have a gradient created using our colours but I wasn't happy with the execution - ideally I would be looking for a diagonal gradient adding in some white to offset the brightness of the pink I would also like to see the gradient used translucent over imagery.
I am attaching a template that we currently use that we would like to see updated but also we are looking for some added template pages for graphs, data quotes etc... to help us create an extensive sales deck.
Also attached is a couple of examples from a previous employer that I feel is the look we should aim for in regard to accent colours, layout and the gradient (do not replicate the colours).
I have also attached our brand guidelines.
