A inkscape tip (about arrow tips)

If you are working with Inkscape, and if you want nice SVG graphics you should be using inkscape, you may have notice that when you add a path/arrow with a tip, and then you want to change the color of the arrow, the head will remain using the old color. Why this works this way is something I don’t understand, but how do you make them match?

Well, you select the arrow(s) you want to modify, and then Effects->Modify Path-> Color Markers to Match Stroke

Nice trick, I found it in Here
