A presentation slide has black text on a dark blue background. Why will it be difficult to read?

Answer and explanation

Correct answer: Colour contrast is low

Readability depends strongly on contrast, which is the visible difference between foreground text and its background. Black text and dark blue have similar low brightness, so the letters do not stand out clearly and the reader must strain to distinguish them. Option B correctly identifies low colour contrast. Text length, clear images, and the presence of a title do not explain this specific difficulty.
