What's the problem with black and white stripes? Wider versions are more visible, and stripes have worked pretty well for the past 100+ years. Black pants, with a white stripe, seem to be working pretty well these last several years, and a black cap (with white piping) is still unique (although all white for the Referee is a good way to identify who's in charge).
Does anyone (who wears the uniform) really care about the superficial details (colors, format, etc.) as long as we're clearly identifiable, and the design is consistent from game to game and easily recognizable to players, coaches, timers? Fabric, comfort, easy of cleaning, durability, weather resistant are important, but can be made in whatever design (including black & white stripes).
Fashion police aside, does any of this matter?
