Designing presentation slides
Use high contrast colours (see WebAIM's Contrast Checker).
Use more than just colour to convey information (e.g., combine colour with an icon or text).
Keep text brief and graphics simple.
Use large, sans serif fonts.
Use white space wisely. Avoid overcrowding visuals.
Caption or title all images and graphics if they present content.
Provide descriptive alternative text in your file for all images and graphics.
