There are different possibilities for this.
1. You might have applied material or default materiel property might be tweaked.
2. In View -> Lighting check whether single light source is checked.
3. Check Graphic Properties. (Most likely Graphic Property might be the reason. Check whether the colour is in Automatic)

If this is occurring in Sketcher...it may also be likely that you have applied a color to the overall assembly "instance" piece instead of just the partbody. Just right click the instance and change property color back to "no color".

Asif sir is absolutely right. When we click the lines on the branch it will get deep gray( or can tell Black). That's means the the the parts have got lucked.

it is because u locked part by clicking on branch of model tree.
there is a small white line between part name and + sign click on it and it will appear white again.
