Alex said:I haven't seen this sytainer in person, but knowing Festool's colours it's probably the same dark blue Festool uses for all their tools, named RAL 5004 Black Blue.

On the picture Shane posted it looks black on the front, but that's how it works with Festool Black Blue when the light doesn't hit it directly. The blue is so dark that when there's no direct light on it it looks black.
When you look up top of the picture near the green knob, you clearly see a blue hue around it. That's where the light hits it directly and only then will you see the blue haze.

I'll fess up, I have one of these from Europe. I think Alex's explanation is pretty close. When you look at it in regular inside light, it's looks black. However, when you put some other light directly on it, say from a syslight, you can start to see some blue.
The nylon case that each syslight comes in is blue with black trim. The systainer is much closer to the black trim and is not really close at all to the color of blue of the bag.
Hope this helps.
