High contrast colors can strain the eyes and hide the text

Choose light fill colors and dark text or vice versa for good contrast

Applying too many different colors and fonts in one sheet

Too many styles confuse the reader and reduce clarity

Use a simple, consistent color scheme and font style

Not using borders or separators in tables

Data blends together and is hard to follow
