Mod of the noobs, by the noobs, for the noobs.
This mod can show armor thickness by color. It is LEGAL, I asked Japanese staff with a ticket.
https://github.com/aki33524/NoobArmorMod/releases
Move aki33524.noobarmor_x.x.wotmod and aki33524.noobarmor_colors.wotmod to under World_of_Tanks/mods/0.9.18.0.
If you want to change armor color, replace noobarmor_colors.wotmod. This is uncompressed zip file. It's easy.
armor/x.png corresponds to armor of thikness x-mm.
sarmor/x.png corresponds to space armor of thikness x-mm.
In default file,
under 32mm armor is green. orver 160mm armor is red.
under 32mm space armor is sky. orver 160mm armor is purple.
