More likely to be the Large Yellow Underwing, I have had a few lately and they can be very variable. If you saw the wings open they are bright orange under with a dark brown pattern near the bottom. You will normally only notice the underwing colour when they are inflight, or flitting up a window.

Notice the small dark marks near the bottom outer edges, there is also some vertical striping on the lower border.

Here's one of mine, I have had very dark ones and very pale too. They can be disturbed in the daytime, I have found them resting under the grass edge of a flower bed.
