Visual Studio text editor: how to change the color of log statements?

I am using VS2010 and I have many log (log4net) statements in my code.

if(Logger.IsDebugEnabled)
{
    Logger.DebugFormat("varX = {0}", varX);
}

I do not want to add #regions, because the number of such registration blocks is very large. Is there a way to change the color of these lines to "Gray" to distinguish them from regular code?
