Generally true, yes.W-W-G will look good and C-W-G as well. W-C-G would feel mismatched and off balanced I think.
There needs to be at least two pieces (helmet, top, pants) that match color wise for every set, or the main colors need to be on top and bottom (C-W-G), otherwise it feels off balanced somehow idk.
Now that we have the cardinal jerseys with white numbers, I do think the w/c/g would work, and actually be a nice change from the previous years when we had c/c/g. Especially if they wore white accessories like white socks, white gloves.
