O for me is orange-red brick on an old building in the historic Czech Pilsen neighborhood of Chicago where my daughter lives. A close up behind the ornate bars shows a lovely stained glass window. My eyes are always drawn to the complimentary color of orange=green, in this case my favorite blue green/aqua. Call me 'umm, not very creative' but I've used 'orange' for every O round of ABC Wednesday. Oh well.
See more examples of the letter O from bloggers all over the world at ABC Wednesday, hosted by Mrs Nesbitt. Happy Wednesday!
