There's a certain irony in my not having taken part in Sandi's and Gattina's Photo Hunts last week when the chosen themes (of 'ginormous' and 'rocks') would have been far easier for me to find suitable photos for than this week! Actually, Gattina's choice this week of still life isn't too difficult on its own but Sandi's choice of indigo required to really put on my thinking cap, especially when thinking of it in combination with still life!
In all honesty, about the only time I use the word indigo is when talking about the specific colors of the rainbow. In fact, I talk more about 'indiglo': that is the electroluminescence display feature of my old Timex watch that makes me love it so -- and had to look up which shades on the color spectrum make up indigo on Wikipedia!
After doing so, I found a photo I took while out hiking of beautifully indigo-colored sections of a plant (which, bad naturalist that I am, I have to admit to not knowing if are fruits or seeds!) that I'd like to suggest to artists as candidates for incorporating into still life paintings. Perhaps the one who painted the colorful floral still life I saw while visiting his studio during the 2012 Fotanian Open Studios may be one of them? ;b
