Dear MathGroup, 

  is there an easy way how to change colors of some edges in 
graph? I think I can use this solution:

http://mathforum.org/kb/thread.jspa?forumID=79&threadID=1863422&messageID=65
16576#6516576

(only for edges) but it seems to be a little clumsy.

This is my graph:
====================
GraphPlot[{"v9" -> "v1", "v9" -> "v5", "v9" -> "v7", "v9" -> "v4", 
  "v5" -> "v2", "v5" -> "v0", "v7" -> "v0", "v7" -> "v3", 
  "v2" -> "v1", "v3" -> "v4", "v2" -> "v6", "v0" -> "v6", 
  "v0" -> "v8", "v3" -> "v8", "v6" -> "v10", "v8" -> "v10", 
  "v1" -> "v10", "v4" -> "v10"}, VertexLabeling -> True, 
 VertexCoordinateRules -> {"v0" -> {0, 0}, "v2" -> {-2, 0}, 
   "v3" -> {2, 0}, "v1" -> {-3, 0}, "v4" -> {3, 0}, "v5" -> {-1, 1}, 
   "v7" -> {1, 1}, "v6" -> {-1, -1}, "v8" -> {1, -1}, "v9" -> {0, 2}, 
   "v10" -> {0, -2}},
 EdgeRenderingFunction -> ({Black, Thickness[0.0030], Line[#1]} &),
 VertexRenderingFunction -> ({LightGray, Disk[#1, 0.25], Black, 
     Text[#2, #1]} &)]
===============

And I want to change color of several edges - not many.


Thank you for any help!
