What you can do! Color Universal Design

More things you can do! Select colors that are easier to distinguish (e.g., ColorBrewer) Ensure that there is enough contrasts in brightness & saturation between foreground and background Make texts or objects as thick or BIG as possible Caution when using RED

Resources ColorBrewer
