Gray is the Way

I'm in value boot camp and nothing is as it really seems when it comes to lights, darks, reflected light and local color. The whites can't be too white or there's no room for the highlight. So what color would 'read' white, but not be straight from the tube white? 

Grays. Green gray, violet gray, orange gray ad infinitum. You can mix endless beautiful grays. I'd like to say that I finished this but I wiped it because I veered off the path and created mud. 

It happens.
