It’s still cold in the evening and our family room/tv room gets VERY cold at night. So, we’ve been using the fireplace almost constantly. Tonight, on a whim, I bought one of those Duraflame multi-color fire logs. For most of the night, it was pretty normal. But now it’s got these wild blue and teal flames on the bottom and a mixture of blue and normal orange above. I suspect that as the log burns down the colors will get stronger as it seems to be the less high flames that carry the colors. It’s a nice way to end a long day.
