Default Which metals are in which soft glass

Partially for curiosity and partially for knowledge for an idea I have, I want to know which metals are in what colours of soft glass. I am new to lampworking, but I've heard pinks need to have gold in them and some colours react to others because if the copper etc. And the whole silver glass thing (I'm assuming they contain... silver), and what about iron, nickel, brass etc. I would like to know generally what colours contain what metals, or even as specific as possible.
Is there a list somewhere that list what glass colours contain what metals? Even for the sake of reactions?
If not, feel free to post any links or specific colour/metal info you know.
(Google has not been helpful for me)
Thanks!

I used to have a graphic w/info., but can't find it offhand.

However, Google brought up a batch of things in answer to What makes glass different colors. Among them:

https://en.wikipedia.org/wiki/Glass_...%20to%20yellow.

I think Kay (listenup) still has a website with, seriously, tons of information about that kind of stuff.

I think the Bulseye website does too although that glass is stiffer 93 / 96 used in fusing and stained glass work, the color makeup is still pretty much the same.

Thanks, sometimes finding the right search words really helps. The geology link was especially helpful.
I looked through the listen up and bullseye websites but I couldn't find any references to which metals are in which colours, but maybe I am just bad at searching or navigating.
Edit: never mind found the bullseye info in 'about our glass' link, instead of by search

The Bullseye site is a bit difficult to use, but has a wealth of information. There is a PDF that shows all of their colors and the compounds that are in them. If I can find it, I will add a link.

Here are the charts. This is specific to Bullseye, but can generally translate to other glass. http://www.bullseyeglass.com/methods...ity-chart.html
