Yes, I realised I was a bit off topic just after I sent the message! I agree that to get get colour accuracy a chain of calibratewd devices is needed and as you say a a colour swatch goes a long way towards this. As to my tip, the ColorHug us only good for calibrating screens, no good for camera or printer. There are other devices that will do this.
