Hi Mike.
I got your sample yesterday. Thank you. First off, I compared it with what I could see of it on my computer screen and there is quite a difference - much darker on the screen. All computer screens vary in colour so no great surprise there. Then I compared it with my original sample. It is a perfect match. It needs to be looked at in good daylight. Not bright sunlight and not a dark cloudy day. It also needs to be looked at between the hours of 11.00am and 2.00pm to see the true colour, because the sunlight is bluer in the morning and redder in the afternoon and this changes the observed shade of a brushing. When comparing Precision Paints colours this should always be done against a neutral grey background, and brushed out onto white, glossy card, because the original formulations were made, brushed out on white glossy card, and any other base will alter the resultant shade.
The Stroudley livery was quite complicated and there are a number of colours adjacent to the main colour. To get the correct visual impression, the full lining needs to be added as well, because the eye sends the colour combination to the brain and the brain evaluates what the eye sees. The other livery colours are darker, and the brain will see the main colour as lighter than if there was no lining close by. The other point I would make is that the brain can only remember a true colour for about 3 seconds after seeing it. It then remembers the colour progressively as lighter and brighter the longer ago the colour is remembered from. Also, the smaller the sample being viewed, the darker it will appear to the observer. Another problem is that many people see colours slightly differently. They are not colour blind, though 20% of the male population, and 14% of the female population, are to a lesser or greater degree, but to others, their red and green perception may be slightly increased or decreased, and this will effect the resultant shades that the brain sees, with browns particularly, because red plus green make brown.
I hope that reassures you about the Precision paint you have. Most people think that Stroudley's Improved Engine Green is lighter because they are remembering Boxhill. I don't know if Boxhill has been repainted, but when it was restored by the LMS back in the late 1930s, they used standard yellow ochre, not the Stroudley shade which is quite a bit darker. I was very lucky that British Railways found the tin of Stroudley paint that they used to paint Western Courier, otherwise I would never have got a sample of the true shade.
