Coloring Multiple Bricks in LEGO Digital Draw
Yes.

I'm using:


Version (Program): 4.3.11.
Version (Brick): 2670.
OS: Windows.


Pre Setup:

We're using Extended Mode (Black Backsplash) of LDD, so we can have full access to all colors.  I have not tested the other two modes, Default (Blue Backsplash) or Mindstorms (White Backsplash).

If the model is in Default Mode.  No problem.  


Copy the build to memory (CTRL+A) then (CTRL+C);
Open a new blank file in Extended Mode;
and Paste from memory (CTRL+P);
Give file a different name as not to overwrite the original;
Re-save.


Setup:


Use the "COLOR Selecting Tool" and select a piece's color you want to
change.
All of that color is now highlighted.
Use the "Invert Selection Tool" to reverse highlight everything not
that color.
Use the "Hide Tool" to make everything not that color disappear.
Use the "Single Selection Tool" to block select the visible pieces
that are getting a color change.
Use the "Paint Tool" and pick the new color being used.
Click the "Show all hidden bricks" button.

Done.


In Program Example:

Goal:  Switch Mega-Man blues into Leaf Shield greens.
