Please note: I did get pooped on from unhelpful finches while getting some half decent photos of the females.

Here's my normal silver from the side:

My camera likes to enhance colours that aren't really as bright as they seem sometimes. I'm still working on a better photo of the lighter silver.
The silver have the same pattern as the wild type but in grey and the lighter silver still shows the pattern but much lighter.
We haven't got red breasted, blue face, pearl, or whites here. I know combinations of colours/mutations are possible and that affects the patterns on their feathers. I love the blue face ones.
Most males should have the red on their tummy but the red breasteds have a lot more, right up to their chins and up into their wings, and they also have a different bib with a thicker band of black/grey and just a very thin white line under that.
This site shows some caramel females and a silver red breasted:

I am trying to get a photo of a chick, female and male in each colour but it's a work in progress.
Here are what I call caramel (top) and cinnamon (bottom):
