Shell splash dyes versus colored muzzle flashes

Did navies try to give each ship a distinctive muzzle-flash color as the Japanese did with colored shell-splash dyes?

Several navies experimented with identification methods, but the Royal Navy concentrated more on suppressing muzzle flash through flashless propellant.

Navies experimented with different ways to distinguish ships' fire but chose varying solutions. The British priority was to make propellant produce less visible flash, especially valuable in night actions, rather than deliberately generating a unique colored signature that could reveal the firing ship.
