good point, I was never really satisfied with simply drenching my tiles in color, perhaps its best to think about some inherently more colorful props.
@Decroded
that would be a shame, thinking of the possibilities of future roomba technology

Oh, I could easily do more pipes, feels like most of my tilesets atm are made up of pipes

(not even using the full set on the above image actually)
I'll focus on getting a basic collection of tilesets together for now, next was actually going to be an outdoor set.
