RMweb Gold TheSignalEngineer Posted June 20, 2019 RMweb Gold Share Posted June 20, 2019 What type of light are you looking at the coaches in? Different colour temperatures will make paints apparently change shade. Fluorescent lights and some energy saving ones can give a picture a decidedly green tint. 1 Link to post Share on other sites More sharing options...

If you look closely at the release photo of the first coach in the first post it clearly has a green lower band instead of choc brown. I have noticed this on the coaches in the Bristolian set as well and as you can see from the photo below comparing one to a Hornby autocoach there is a distinctive color difference here. I have looked on the various GWR modeling and prototype websites and can’t find mention of green instead of choc brown being used on the coaches. Can anyone explain this to me, thanks. Sorry but I don’t see green anywhere. 1 Link to post Share on other sites More sharing options...

It is not green, it's a different shade of brown, I have a set of these and it is definitely not a variation on green if you think it is you are colour blind.

As shown in my attached photo I have cars with both colors and there is nothing chocolate about the coach on the right. The RH coach definitely looks to be dark brown to me. If GWR coaches had been produced in dark green, there would have been an outcry amongst the numerous GWR fans in the UK. They may look to be dark green to you - but everyone else sees them as dark brown. Regards, John Isherwood. Link to post Share on other sites More sharing options...
RMweb Gold Harlequin Posted June 21, 2019 RMweb Gold Share Posted June 21, 2019 (edited) Colour perception is subjective and people can see the same thing in different ways. Remember that widely publicised meme recently about the dress that some people though was gold and others thought was blue. I don't see "green" but I do see a colour that is "greener" - so I can see what Cofga means. FWIW: If you use your favourite graphics program to sample the pixels in Cofga's image they do have a slightly greener hue on the Collett corridor than the Autocoach. That was just one pixel on each coach - possibly an extreme case. To assess it properly an average would need to be taken under controlled lighting.

RMweb Gold TheSignalEngineer Posted June 21, 2019 RMweb Gold Share Posted June 21, 2019 Thinking from the point of view of mixing paints at junior school. Red plus green equals brown. More of the former you get a red-brown shade and more of the latter a green-brown. 1 1 Link to post Share on other sites More sharing options...

As soon as you go oil-based it becomes much more complicated than that. I recall having some dark red paint mixed for me and being very surprised that the main pigment involved was a cobalt blue.

Cofga Posted June 21, 2019 Share Posted June 21, 2019 (edited) I used it consult for LifeLike on their Proto 2000 paint schemes and I know that what comes back from China can surprise you. We once sent instructions for the paint on a US Southern Railway diesel that called for Southern green (similar to UK Southern green), imitation aluminum which is a light gray, and imitation gold which was a yellow the color of mustard. The test shot that we got back from China had the correct green, but the aluminum was metallic silver, and the yellow imitation gold was metallic gold. It made an interesting locomotive paint scheme but it would have been a total disaster if the production models came that way. Walthers eventually bought LifeLike and they still can’t get the green or the imitation aluminum correct, so if you guys are happy with the dark green chocolate brown coaches then I doubt anyone over here will challenge me when I run them behind a King class as an excursion train on my HO Southern Railway layout!

Be assured - such is the fanaticism of GWR fans in the UK - if a model GWR coach had been issued in anything resembling green you would have heard the howls of protest in Western North Carolina, without the benefit of any form of electronic transmission !!!

RMweb Gold Market65 Posted June 21, 2019 RMweb Gold Share Posted June 21, 2019 Good evening, everyone. I’ve read through all the posts regarding a green lower ‘band’. I’ve looked at the first carriage pic on the first page. I’ve enlarged it as far it will enlarge to. There are greens and purples to be seen which I think are artifacts of some kind. It may well be these artifacts which have given the impression of some green in that area. Personally speaking I’m unable to see any green at all when looking at the pic normally. Only when cruelly enlarged, along with the purple splotches too. Here is a part on the enlarged pic. I hope it will explain things more clearly. The greens and purples are just below the divide between the cream and brown. Best regards, Rob. Link to post Share on other sites More sharing options...
Steamport Southport Posted June 21, 2019 Share Posted June 21, 2019 I've seen green GWR coaches. But that was just mould and rot.... It wasn't called the Green, Wet and Rusty for nothing. Jason 2 Link to post Share on other sites More sharing options...

Steamport Southport Posted June 22, 2019 Share Posted June 22, 2019 In a previous thread where there was an argument about colour somebody posted an online test where you could test your colour sight.

RMweb Premium Ian J. Posted June 22, 2019 RMweb Premium Share Posted June 22, 2019 (edited) This one? https://www.xrite.com/hue-test Edit: the more difficult one as well: https://xritephoto.com/cool-tools# According to both I have a score of zero, which means perfect colour vision. However I know I have a tiny difference in colour accuity in each eye, as others above have mentioned. Edited June 22, 2019 by Ian J. 1 1 Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted June 22, 2019 RMweb Gold Share Posted June 22, 2019 (edited) Me too, although the rest of me is in a terminal downward spiral... I am not aware of any difference in colour acculty between my eyes, but that doesn't mean there isn't one! I suspect that as well as JPEG compression artifacts some of the images are picking up some green reflection from a nearby object. GWR coaches of the period in question are painted brown and cream, and only camping coaches carried a green and cream 'tourist' livery.

RMweb Gold tomparryharry Posted June 22, 2019 RMweb Gold Share Posted June 22, 2019 (edited) Having just taken the test, I've scored 46, in a range 0-1600. Not too bad, but has been better. Luckily, I can still spot a pint of cider from 50 metres, when placed upon the bar! Edit: After re-taking the test, I managed to reduce my test result down to 2. I'm very happy with that, considering that 2 years ago after my stroke, my left eye was kaput. That said, you can argue to the ends of the earth about Brunswick Green, and Mid Chrome green......

88D Posted June 22, 2019 Share Posted June 22, 2019 I’m amazed that nobody has mentioned how brown the Hornby colour is for their GWR locos. I speak as someone who has perfect vision - when I was tested in 1968. Time to go gardening. 2 Link to post Share on other sites More sharing options...

robertcwp Posted June 22, 2019 Share Posted June 22, 2019 Useful test. I quit whilst I was ahead after the simple one, with score of 0. I know my eyes are bad in some respects but my optician did comment that I had good colour perception, which this seems to bear out. Link to post Share on other sites More sharing options...
