Green. Holds mail nicely. Very mailbox-y. 
Nice flag, Thrilling in its heart pounding red, an exciting visual beacon trumpeting a resounding and heroic note to my mailman that I am at long last ready to pay the water bill. 
 I leap out of bed every morning, like a kid on Christmas morning just to check my mail because this mail box has blessed my life. I don’t know what I ever did without it. I’m thinking of getting one for my kitchen to keep bread in.
