Description

Applications need to be compliant so that colour blind users can use our applications.

For starters, the default colour scheme is blue text on a black background and I think this is an issue.

Awaiting formal guidelines before this can be actioned.

• Check that the current scheme is not suitable for accessibility issues
• Update colour schemes if required.

I feel like the best way to move forward is to do the following.

1. Research colour-blindness compliances
2. Assess current scheme for conformance
3. Quick wins - change graph labels default to white instead of blue. Anything further noted for point 2.
4. Create a scheme using css files to allow easier switching between either a light/dark theme or a high contrast theme.

This would mean that the ticket relating to .css file merging would need to be done prior to consolidating the theme into one file.
