For what it's worth:
It sounds like you can't get more of that green (just to view it for another decision) so that is out.
The red makes it look like a poinsettia, very apropos.
The white makes it look like a wreath, also apropos.
The gold is my favorite, but it's too brash; needs a softer one to match what's in the red print.
How long is your runner? If you use all three somehow, it might work, but will not look as elegant.
Guess gold is best, but again, that one is just too brash.
If that's all the fabric you have to work with, then RED is my final choice, but in the end, it's your project. Good luck.
