Tips
for accessibility
2.
Ensure that contents can be easily accessed even without the use
of colour
Users with colour deficiency may not be able to differentiate the
different colours and may miss out information that is presented
in colour alone. A good colour contrast will help them to read the
information clearly.
Suggestion -
Test the colours used in web pages against a black and white printer
or a monochrome screen. Ensure that a sharp contrast is displayed.
Examples -
The text in the button on the right is much more distinct than that
on the left.
