How do you change part color to a specific RGB?

Let's say your part is blue and you want to make it blue gray, how do you do it?

1) First, you would go to Menu --> Information --> Object --> Set selection filter to solid body --> Select the solid part --> Ok -> you would see the color number listed in Information window, for example as below:

Color 129 (Medium Steel).

2) Then you go Preferences -> Color Palette -> In Find box:

Type 129 --> Select the color in the box --> In Selected Color group --> Select the color --> Colors window pops up --> Select Custom --> Now you can change the RGB (Red, Green, Blue) by pressing the arrow up or down as desired --> Ok

Now you should see the new shade of blue.
