Haha, same for me, downsizing, Going with golden Oak

Popular trends vary by region. Right now in the upper midwest my trend has been dark (yuck!) but it can change in a heartbeat.

You need to figure out the brand of stain you plan on using first because different colors are named differently by different brands.

Then figure out how dark and how much red you want.
Duraseal (minwax) has a color called Medium Brown.
Buy some sample size cans and play around with colors.

The swatches they give out are junk. Primariy because the size is too small and one color will look different on brand new wood and look different on a 50 yr old wood.

The co-op is my daughter's. We get to play along!
Thanks for the info. I think I'll try to collect pictures of what I think will look good and go to a flooring place.
It seems the medium browns are in right now, but I thought maybe they are called something that I could research.
