Overview
When achieving color accessibility, there are many factors that need to be considered. We have focused on the following aspects to ensure that the materials we create for Wiki and Education are accessible to everyone:
- Use blue or orange instead of red and green, as they can be difficult to distinguish.
- Avoid using only warm or cool colors; alternate between warm and cool colors.
- Ensure clear contrast in color shades so that they are distinguishable even when printed in monochrome.
- Emphasize text using light blue, orange, or underlines (avoid using red and green).
- Create diagrams that can be categorized by patterns, not just by colors.
- Avoid increasing the number of colors used.
