If you’re color-blind, or if you ever shot wrong shell by mistake… You may want to use this mod.
Screenshots are all explanation you need.
Note: HEAT and premium HE shells are gold-colored by this mod. This however does not always reflect premium status of specific shell. This is mostly visible with APCRs, which on many tanks are now standard ammo while still premium on other vehicles. The mod only changes game graphics, so it cannot reflect actual shell premium status. Sorry!
