Color Converter DSP

I get the following error on compiling my application:

The type or namespace name 'CColorConvertDMO' could not be found (are you missing a using directive or an assembly reference?)

which relates to the following line of code:

typeof(CColorConvertDMO).GUID,

Where is the CColorConvertDMO CLSID located and how do you access it?
