Being able to have some kind of masks or masking tape for the color gun would be nice, as an example: we could have an upper block mask which would mask out the top half of the object so the color change would only apply to the upper half of the object, there would also be a lower version, there could also be a flame mask which, you guessed it, allows you to paint flame patterns, we could also have horizontal and vertical stripe mask. This would not just apply to buildings but also machines and everything that can be painted in general. Also, I'd like to mention that this would NOT be a thing applied to the color preset, but rather it would be something that is applied to each object individually. I personally think this would give us a lot more options in terms of styling our factories.
