Guaranteed it would have been nvidia's choice for the colours.
Along with the nice big fat pay cheque they give DICE/EA to include the ray tracing and gimp the built in frostbite graphics engine's reflections/shadows etc. in order to make ray tracing look a lot superior than what it really is...... they would have wanted the game to be colourful in order to emphasise the ray tracing effects even more i.e. have the reflections etc. pop out even more, their rtx ray tracing demo of the tank and flame flower makes this extremely obvious.
