Change color of crosshairs

How can I change the color of the crosshairs. I have a lightgrey background. The crosshairs are light yellow.
In the printscreens for my manuals you cannot (or only very difficulty) distinguish crosshairs and background.

see a small video as sample:

Thanks for your help

I will see whether we can add a feature to support this.

just invert your background image  ;)

Thanks,
if you have watched the small video you saw how much effort I needed to draw a tangent. and this tangent is not "constructed", it is just an approximation, it is not the real tangent between the two circles.
Would be good to have a snap "tangent" or a snap"construction points" which snaps all construction points like middle, end, center, tangente...

Sorry - the request "tangent" was unnecessary. The tangent can be drawn with "lines">"tangents from cicle to circle"

"The manuals are printed."
Was thinking you want to use it for videos.

If your work will be available freely and for everybody, could you please post some links to your manuals.
At least it would be nice to have a link to  "Design Knittings with LibreCAD LESSON 1".

 And put it in http://forum.librecad.org/LibreCAD-Tutorials-and-Manual-Wiki-topics-f5707542.html .
I think this post/topic should be moved to http://forum.librecad.org/Suggestions-and-Feedback-f5706791.html .
thanks.

We can implement snap perpendicular, parallel/tangent in 2.1

The only limitation we face is development time. We hope new developers would like to join us. Another thought we taking code from other free CAD software (someone said gnucad).
