Changing the Color of a Part

Select the "Parts" tab.

Select the Color Cell of the part you wish to change.

Select the color in the color window. Press "OK".

Trick:

If you'd like to change the color of multiple parts at once, go to the "Edit" tab and the "Misc" sub tab.

Click the "Color" button. Choose a color. Click directly on the part(s) to change its color to the selected color.
