Not too long ago, I was creating a webinar when I ran into a minor problem. I had to choose a new background because the one I had been using had a number of issues. It made me think about the problems involved when choosing your slide backgrounds.
In this article, I’m going to share five rules to help you select a background for your presentation slides when you deliver a webinar.
1. Keep it simple. I’m not referring to visually simple (at least not here) but rather physically simple. One of the most powerful techniques for creating backgrounds consists of layering flat colors, photographs and effects. This can create very flexible and visually stunning backgrounds. Unfortunately, some of the webinar hosting companies are unable to properly process these backgrounds. Remember that none of the hosting companies have access to the actual software used to create presentation slides. They are attempting to emulate it. That means that some effects at the edge of capability may not reproduce properly.
2. When creating your background go for high contrast colors without being garish about it. Colors which are opposite each other on the color wheel are considered high contrast. Black on white, white on black, red on green, orange on blue are all high contrast. As a result words are easy to read because lines stand out on them. Effectively, your audience won’t have to expend as much energy to read your slide. However, watch the colors and the intensity as some combinations may be too vibrant. The result will be just as exhausting.
3. Don’t let the writing overlay any pictures you use. To a certain extent you can overcome this by tinting the picture. This hints at a picture by using different shades of the main color as shadows or highlights. Unfortunately, this means that lettering may become lost in the shadow or highlight. Very few colors for the lettering will display clearly over multiple shades of a base color. If you are going to use a picture — and there are many reasons to do so — keep the picture to the corners where they will not have to have lettering placed on them. This applies equally to logos as well!
4. Don’t be too strong with your background color. Light shades and low intensity colors are more forgiving than high intensity or dark colors. Use the dark, high intensity colors for the lettering. That way your words will be much easier to read.
5. Remember that you don’t control the actual colors seen. The actual color seen will be interpreted by the hardware on the viewer’s desk. There is a great deal of variation in the colors displayed by different makes and models of terminal. Even one make and model may vary from unit to unit. So be careful when picking colors where precision is required. It won’t happen and your slide may be unviewable.
