This code also changes the color of the frame of text labels (if it was 
displayed).

The ideal expected way would be:
ca.children.children(2:2:$).foreground = color("green");

But this instruction yields an error. This is a bug, just reported here:
http://bugzilla.scilab.org/15079
The proposed solution shall be available in Scilab 6.0.1.

Before it, you may simply do the following:

edit %h_get
// in the file, replace the instruction
out_vect=[out_vect,get(hdl(i),str)]
// with
out_vect=[out_vect;get(hdl(i),str)]

Then exec %h_get.sci
If you want to have it fixed permanently before the 6.0.1 release, you 
must recompile the graphics library:

cd SCI/modules/graphics/macros
predef clear
genlib graphicslib
clear %h_get

and that's all for ever: Then the syntaxes
ca.children.children(2:2:$).foreground // reading values = extraction
ca.children.children(2:2:$).foreground = color("green"); // setting 
value = insertion
will work even after restarting Scilab
