hi..
it is not possible to change the color directly.. one method that all guys mentioned works for it

but i have a BETTER METHOD.. by using scope viewer..
1.right click on any block in the simulink. then click on "signal & scope Manager"
2.then a window opens with two major sections""generators" na "viewers" on the left side
3. select"viewers -> simulink -> scope" .. double click on scope.. u wil get it on right side.
4. select it and right click on the signal (below)and click"edit signal selections". select the signal u want to see on the scope
5.then double click the scope (above) .. then u can see a scope with grey background.
6.run the simulator. unlike the usual scope(with yellow signal), the signal color is blue.
7. maximise the scope and click print sceen button on ur keyboard.. paste it in MS Word 2007
8. if u still want the background color in white(rather in grey)double click the picture -> click "recolor" at extreme left of the MS office window ->"set transperent color"-> click on the grey area of the pic.

there it is..

i hope it is very useful.. it may seem bigg process, but actuallyy veryy smaall and easy process..
thank u
