Text, graphics, and images are understandable when viewed without color. Text should be used as a primary method for delivering information.
Review These Explanations
Learners who have low vision or are color blind need high contrast between the text font and background in order to read. Using color as a highlight may not be readable by all learners, and they can miss out on key concepts if only color is used to make specific information stand out.
According to statistics:
- 15% of the world’s population have some form of disability, which includes conditions that affect seeing, hearing, motor abilities and cognitive abilities.
- About 4% of the population have low vision, whereas 0.6% are blind.
- 7 to 12% of men have some form of color-vision deficiency (color blindness) (O’Connor, 2014).
In many cases, these conditions make it difficult to distinguish colors.
