Color Mode
When outputting to 35mm slide film you should utilize the RGB color mode. If you are used to designing for CMYK printing this may take some getting used to.

It is important to work in the proper color mode to ensure the most accurate color possible. If you design in CMYK the camera will have to convert to RGB and color variances will occur.

RGB is a larger color space, so it is best to scan or create your image from the start in RGB. Converting a CMYK image to RGB can cause problems in the translation process.

Color Accuracy
It is important to check the actual values of the color created rather than trusting your monitor.

All monitors display color differently so you cannot always trust that what you see is exactly what you'll get.

We highly recommend you design one or two test slides for output first to familiarize yourself with the nuances of film output if you have color concerns.

Color Choices
Slides display best with significant contrasts of color. Because you will usually be in a darkened room it is best to use dark colors for the background and light colors for the text.

For instance, use a dark blue background with white or yellow text.

We do not recommend using light colors or white as a background for a variety of reasons. A white background will cause so much light to be thrown onto the screen that your audience will have trouble seeing anything at all. Also, a white background will cause all other color to be washed out.

Do not use patterns unless you create an actual postscript pattern. The standard patterns available from your software will not output to a film recorder. Use colors to differentiate between objects instead of software-generated patterns.
