First of all, these principles are basic art class principles. Color is extremely useful in presentations, but note that there are some rules to observe.
Most missionary presentations use very few title slides, but some use a background kind of effect with an image within that “frame”, and a title. The frame and title would be where you would apply the principles in this post.
There is a very useful and nice program called VideoScribe that allows you to make a whiteboard type video, where a hand actually draws the image. These color balancing tips come from their website (you don’t have to use their program to follow this tip). I will use there images and add logos of companies to illustrate what they say.

I will summarize the rules here.
