Presentation color
The late Steve Jobs was a master presenter. Part of what made him so good was the simplicity of his Keynote presentations. Here are 10 Presentation Design Tips from Envato that can help you create a more compelling presentation.

My two pet peeves: Color and repetitive obviousness.
Bad color combinations can absolutely destroy an otherwise good presentation. It’s easy to use a decent color palette, but a unique and bold color combination can really make your presentation memorable.

Repeating the obvious drives me batshit crazy. Please, for the love of God, don’t place your logo in the corner of every slide! And if you’re pitching company X for their business, don’t put their logo on every slide either—they know who they are, and they probably remember who you are since you probably just told them on slide one.
