Material colors are not imported through collada converter by default. You should use material color shader, which can be found
here and then edit the material. You may also want to read the whole thread that I linked to, because it covers practically the same question as yours.
First of all,thanks for reply.
I have read the whole thread that you showed to me.and I got the way to solve my problem.That is,first I should get an additional shader to process the materal color shading,and then pass my materal color through an uniform in the material xml file.
That seems make sense when I only have several models to convert.but for a large number of models,it would time consuming.I am thinking if .dae file contains model's material color,if it does and if someone makes a patch to the converting tool would be helpful.
