We rely a lot on colour within our code within our team to outline features that need working on and what needs attention, we we think can be improved (we mainly colour the line of the code) for the application we're developing, however we have a close friend that is colourblind and he wants to join our team despite our heavily reliance on colour. Do you have any other recommendations as to how a team can highlight what needs work on without the use of colour - our team is about 25 people that are all accustom to the line colouring system and we have found it be most efficient.
