Rat,
This is indeed the traditional section, but there's no reason why we can't take the lessons learned elsewhere (like on the modern side) and apply them to our traditional firearms. I would hazard a guess that somebody, somewhere, some time long ago, actually tried to use white paint on his squirrel gun sights. That fer me makes it fully qualified as "traditional" ;-)
As Keith mentioned, red is nigh-on impossible to see. But yellow or amber in fact isn't the easiest to see. There was a post about this on the modern firearms side in which the human ability to see colour was discussed in some degree of detail. The graphical evidence presented there showed the human eye has a strong preference for colours in the green/blue band, and even more so as we move from normal day vision to "night" or low-light vision. If we choose white as our sight colour (ie white dots on the front and rear sights) we stand a better chance of seeing the sights because those dots are reflecting all colours of light toward our eye.
OK, I'll hop off my soap box now. But just before I do, please keep in mind that my reference to my Traditions Pursuit was to its fancy modern sights, that as fancy and modern as they are, just can't be seen in low light. In fact, my painted "traditional" sights on my "traditional" Hawken-style gun beat the daylights out of the fibreoptic ones, so this is one of those happy times when high tech doesn't necessarily equal high performance!
