Playing on Xbox 360, I have been really getting into the player-made houses, and am currently building a set of "showcase rooms" for my painter.
I have placed 16 2x2 segments of wooden wall to display the base colours, and framed them with stone, to display the deep colours. Everything is pretty much complete. However; Deep Cyan does not appear to paint stone. I know that some tiles can not be painted, but I understood that this was specific to the tile, not the paint. As you can see in my image, I had no trouble painting any of the other frames.
I have attempted to paint the stone with Deep Cyan twice. The first time, you could see the tiny paint drops flick out, confirming that I had painted something. The second time, I cleared out my inventory, to make sure I was not accidentally using a different paint. This time, no paint drops, and still no colour.
Does Cyan/Deep Cyan Paint have different capabilities then every other paint, am I doing something wrong, or is this more likely just a bug?
