Red-green colour blindness affects approximately 8% of males and 0.5% of females globally.

The shades of green, yellow/orange and red that represent good to bad solutions in the survey tab as well as the image frustums are very difficult to differentiate for people who are red-green colourblind. Obviously these visual inputs are very important for resolving errors in the AT.

I suggest:

• not relying on colour alone to convey meaning. Other visual cues such as symbology or text labels will help.

• A lot of research has been done in software design for this issue, and colour gammuts that convey 'good' or 'bad' to both colour blind and non-colour blind people at the same time have been found.

• Alternatively, having an embedded Colour Blind Mode which switches from green=good, red=bad to, say, blue=good, yellow=bad for everything in the UI.
