Railroad colors

Hey all,


Just a quick question regarding railroad colors...

I'm planning on redoing my Lionel Alcos in Union Pacifiic livery and my Marx E units in Rio Grande schemes...so..

my question is....what colors do I buy? Do I go with straight yellow and grey for the UP locos, and straight yellow and silver for the Rio Grande paint?..

..or, do I try to locate paints that are authentic?

I know Floquil makes a ton of railroad colors, but the paint I found for UP paint schemes looks too orange per the pics I've seen in magazines and on the internet. I couldn't find a match for Rio Grande yellow.

Help, any help would be appreciated


Cheers, Ian
