Whew! It's done! Here are a few pics the first one looking toward the fireplace and the second one at the bottom of the stairway from the mudroom. The colors look different in the pictures but they are actually very similar in real life.
If you want info about staining your own concrete I highly recommend this low cost way to do a really stellar floor! There are tons of info on the web - Don't pay big prices for the stain - explore homemade recipes (I used water and Copperas which is brand name for Iron Sulfate which is a plant food so to speak...the only warning on the label is "may stain concrete!"). Basically you clean the floor, stain the floor (multiple layers as desired), clean the floor, seal the floor. It's hard, time-consuming work but it pays off in HUGE dividends in what you save.
