Combined colours and effect

A few weeks ago I posted on Meng's T-72B3, their colour set and how after laying down the base coat colour even though it didn't look right I continued anyway as it might look right after the other colours applied, the image to the right shows the proof behind the concept. How we see colours is based on a myriad of effects eg. light colour, surface texture, atmospheric conditions, viewing angle and as shown by the image to the right colours next to the colour we are viewing. While we as modellers are sometimes guilty of searching for exactly the right shade when after weathering, clear coats and different display conditions our perfect shade may not be so perfect anymore sometimes our cause is vindicated...
