Terminal emulators - rgb values for amber, green?

[Jeff Davis]

I was just setting up Tera Term Pro on my windows box (talk about overkill -
1.4Ghz and 768MB to run an ascii terminal!) and was configuring the colors,
and realized I always fiddle around with the RGB values until they look right.
I always create one config for amber on black, and another for green on black
(I'm moody and sometimes use one, sometimes another).

Are there "standard" RGB values for Amber and Green monochrome monitors, or
did each manufacturer make them different?

What color schemes do you use?  How about terminal emulators?
