Does anyone know the RGB (as in painting packages) for various railway 
colours?

I want to do some colours on my web site

Thanks

I don't think that will work, as such. I have a Dell running Linux,
a Risc-PS running RiscOS, and another Dell running XP on my desk - 
all of them dispay a given site in wildly differing colours.........

The colours only display differently - if you connected a single colour
printer to each in turn and printed the same illustration you would get
consistant print outputs.
However, if you connected different printers in turn you would get
different print outputs.

Bottom line, you have to adjust the RGB output to your specific printer
to get the right colour printout. 
Getting the correct theoretical RGB mix in the first place is a good
starting point for minor final adjustment.

Then you need to adjust one or more of the displays. It's "easy" to
make them all the same, getting them correct is a little harder ;-)

Not too easy - two are TFT, one is CRT!

As other posters have stated, that's essentially impossible. Everybody's 
monitor and printer would have to be calibrated to exactly the same 
colour standards for this to work.

Anyhow, most people have wildly incorrect notions about colour 
perception, and hence of "correct" colours. The fact is that there are 
no "correct" colours for model trains. There are only colours that look 
more or less right.

So, what affects colour perception? My reading, discussions with other 
people, and personal experience result in the following conclusions. 
(I'm ignoring colour blindness.) A, B, and C are IMO the most important, 
the rest are in no particular order. Keep in mind that colour is part of 
the illusion of realism that we wish to achieve. "Correct" colours may 
or may not contribute to that illusion.

A) Ambient light is the single most important factor. Any colour will 
look different under incandescent and fluorescent lights, for example. 
The dominant colour(s) (paint, wall paper) in the room have an effect. 
Colours look different under bright sun and overcast skies. And so on.
	--> To make your models to look right on the layout, use the same 
lighting at the workbench and on the layout.
	--> Attach a lighting system to a portable layout.

B) Layout lighting is much dimmer than outdoor light. Dark colours look 
too dark, and bright colours look too bright.
	--> Choose lighter tones of dark colours, and darker tones of light 
colours.

C) Consistent colour is more important than correct colour. 
Unfortunately, every manufacturer has its own version of GWR Green, for 
example.
	--> Apply thin washes greys, whites, browns, blacks to achieve 
consistent tones.

D) Model paints from different manufacturers contain different toners, 
so they often look the same in one kind of light and different in 
another. Also, different formulations (oil, enamel, acrylic) respond 
differently to light.
	--> Standardise on one brand and type of colour.

E) RAL and Pantone colour specs are set for specific lighting (colour 
temperature), which is different than the colour temperature of layout 
lighting. However, they are consistent, which means that a suite of RAL 
paints and Pantone inks will achieve that consistency that makes for the 
right appearance.

F) Colours weather and fade, making for subtle but sometimes 
surprisingly large variations in the colour of supposedly identical 
rolling stock. Similar variations in model rolling stock are therefore 
OK, in fact will contribute to the desired illusion.

G) Film does not "see" colour the same way as the human eye/brain. It 
also fades. This makes colour prints and slides unreliable guides to colour.

H) Digital cameras vary in their ability to "balance" colours in 
different lighting conditions. The same is true of scanning software. 
This makes digital images unreliable guides to colour. It gets worse 
when the images are printed out.

I) The human visual system is very good at adjusting colour perception 
in different lighting conditions so that a scene looks right. This means 
that with a little help (see A, B, C) your layout will look just 
wonderful! ;-)

On each page about particular railways just wanted some block colour as near 
as possible.

Might have to scan samples and see what they do.

Yes, or find  a web site that uses  the colour you're after and see
what they are using.

As Wolf says, go for the "look and feel" rather than exact colours, 
not least as the results seen by users may not be quite what you
expect. I had red on green on my site for a while, which looked
realy nice with RiscOS, but after a few moans I looked it on the
XP machine and, well arrrrrggggghhhh! - it looked horrible!

I also tried what I approximated to BR blue on my other site - 
you couldn't read anything! I had to make it much lighter, but it
still says "BR Blue era", at least to me....

This site states what has been said above but does give the 'base' RGB
values ......
