I hope you can give me a quick 2-cent comment on the following:

I have an older, 3-story colonial home with (sadly) cream-yellow vinyl siding that we do not plan to remove. I couldn't get the photo to attache but would be happy to send it to you. I have just purchased quality window boxes for the upper windows. I plan to paint the boxes the same grey-green (benjamin moore paint) that is on the window trim and fill with red flowers. I also plan to paint the apex above the steps the same color. Good idea? Any further thoughts/ideas? The door is currently black...should that change? My goal is to draw attention away from the vinyl siding and to add some life (but in a classy way) to the flat-facade of the home without getting too involved in expense or tear-out; and without it looking like lipstick-on-a-pig. Thank you!
