Cannot change object's display color

I’ve tried everything I can imagine to change this set of objects to the default color but it remains black.

Here’s the file. What am I missing?

Hello - this follows the layer color, which is dark gray but not black.

That’s what I’ve set I think.

Shared with CloudApp

but it remains ‘black’

Then one of the struts changed color. I’ve no idea how.

  • I see - even though the color wheel gives a 255 code it’s not actually 255

Hello - if, as in the file you posted, all objects are set to use the layer display color and that color is 100% black, they should display as white/light gray with black wires.
