Okay, so I am used to the previous BYOND versions and all my previous icons have the gray background (mobs and objects typically).

I decided there may have been a new change to the background color, so I just recreated a new game to test, and sure enough even with the default background in the new BYOND version I still get the gray background. What color do I use to make the background clear again, as I recall it previously was gray.

My icons have the square tiles in the backgrounds in the icon designer, but when I run a .dmb file, all the icons show up with as a gray tile with the icon on top.

EDIT: On the map, before running, the icons appear fine. It happens at runtime, when the mobs and objects are given a gray background and do not blend in with the turfs below. What is the solution to this?
