If dark blue text is placed on a black background, what problem is likely to occur?

Correct answer: Low value contrast may reduce readability

Correct answer: A. Value describes how light or dark a colour appears. Black and dark blue are both dark, so their values may be too similar for the text to stand out clearly. This low value contrast can make the text hard to read, even though the hues differ. A lighter text or a lighter background would usually improve legibility.
