It is important that business presentations use a consistent color palette. Text and backgrounds should be in contrasting colors so that content is easily readable. PowerPoint 2007 and newer versions come with a handy color palette feature for different themes or templates. You can use this to decide which color combination will be optimal for your presentation.
Businesses very often have presentations in old PowerPoint formats or PDFs that are updated from time to time but would probably require conversion to newer formats. 24point0 offers a conversion service which can help you convert presentations or other business documents from older file versions to newer ones. If you need to upload PowerPoint presentations to your website as Flash animation, 24point0 can help you do that, too.
