Colours not showing in Hidden Line Removed Display style.

Hello All,

When I am modeling parts in an assembly I give each part a different colour so i know which part is which.

Sometimes when I change my display state to " Hidden lines " or " Hidden lines removed " the edge line will also be in the colour I select.

Other times it will just choose to be the stanard black lines.

Is there a way to control this?
