Help with colorcorrection class

Hi all,

I'm need a help with color correction, in my development script for example I have

 if meditMaterials[5].texmap_diffuse == Color_correction then ( print "ok" ) else ( print "not ok" ) 

But this has not worked, I tried Color_correction colorCorrection Color correction, and nothing has worked, do not know if I need to take for some class / superclass ...

ps. I use the Vray (.texmap_diffuse)

if someone can help ...

thanks in advanced...
