The color brown probably goes unnoticed more than any other color. The prompt today reminds of the things or people in our lives that go unnoticed but provide great support. When you are driving across a bridge, you don't see what supports it but you trust it is sure and sturdy. This is the old trestle in Harper's Ferry, WV that is now a walking path. You can really see how strong the supports are when you step back and away.
Think about something that provides support today. It can be literal, like my example photo, or it can be figurative, something that supports you.
