One of my children "fessed up" to opening the bathroom cabinet, spilling a bottle of something, and not cleaning it up properly. I suspect it contained some kind of bleach. As a result, we have an orange color, silver dollar size stain on our carpet. The carpet is normally brown, high-low shag, with a mixture of light and dark browns. I was hoping someone could recommend some kind of carpet coloring or color matching that won't be too noticeable. Any suggestions are appreciated.
