Camouflage doors

I think camouflage doors would be cool, you would craft camouflage paste with 1 bone meal and 4 DIFFERENT colors of dye. Camouflage paste and any kind of door would make a camouflage door, let say you placed the door on top of a dirt block, the door would look like 2 dirt blocks stack on top of each oth etc. If you used an iron door it would work the same but require red stone to open it.
