People often pick the wrong font-color when creating image captions, or when pairing the color of a text with the color of its background in general. Doing this can make your text almost completely illegible. At the very least, this means people will struggle to read what you wrote and become annoyed.

- Don’t rely only on color contrasts between the text and the background to achieve readability.
- If readability is your main concern, the best option is to use white text with a black outline, as it is legible on all backgrounds.
