What should you do when choosing colors for visuals?

• A. Always use red and blue together for emphasis
• B. Use only grayscale colors to avoid distraction
• C. Use high contrast color combinations (dark text on a light background or light text on a dark background)
• D. Color choice has no impact on readability

Answer: (C)

Color contrast is essential for readability and accessibility in visuals. When text stands out clearly from its background, people can read and interpret information quickly, even at a glance or from a distance, and the reading experience is easier in varying lighting conditions. The most reliable approach is using high contrast color combinations, such as dark text on a light background or light text on a dark background. This maximizes legibility and reduces eye strain, and it tends to work well across devices and viewing contexts. The other options don’t fit as well: using a specific pair like red and blue for emphasis can create confusion for readers with color vision deficiencies and isn’t guaranteed to be more readable; sticking to grayscale removes color cues entirely, which can reduce the ability to distinguish categories or emphasize important points; and saying color choice has no impact on readability ignores how perception and contrast affect how easily information is processed. A practical tip is to test your visuals for sufficient contrast and consider color-blind friendly palettes, possibly supplementing color with patterns or labels to ensure clarity.
