If you were to get ten TV22s and line them up side by side I bet the masks would all be different shades due to fading, cigarette smoke etc. So unless you have a pristine, out of the box TV22 as a reference (I presume you don't), then what is the 'correct colour'? You don't know. So if it was me I'd be less concerned about attaining a perfect colour match (do one's best by all means) but more concerned with getting a good quality, semi-matt finish with a representative, 'middle of the road' colour.
