On a few drawings I have inserted balloons on they come in as different colors. Sorry I can not tell you what colors they are exactly as I am red/green color blind but I can see they are different. The lighter ones (maybe grey or green), if I delete them and re-insert them they come back in black (I think).
Side note - Stop & Go lights for me are actually Yellow, Yellow, and White (top to bottom). I am on the same roads as you, scary thought huh
Thanks in advance,
