[x] - User Control Colours via Colour Pickers.

Approach

After research, I realised that applying filters to accommodate each colourblind setting was not efficient, therefore, I decided that I would try Colour Mapping.

The second approach (current) was to create individual Colour Profiles.

Colour Mapping

This approach was effectively checking each material for a specific colour (default), if this would be found, it would remap to a colourblind mode friendly variant.

This worked, however, it required resetting back to defaults before the user swapped due to how the mapping was occuring. Additionally, I realised that mapping user controlled colours would be more complicated.

Colour Profiles

This approach requires colour profiles to be assigned for each mode and then the user can merely swap between these profiles. This approach is a lot faster and it also allows for dynamic swapping.

Additionally, this allows for me to create a custom profile that can easily be manipulated by colour pickers by merely updating the colours within the profile to match the user selected.
