Ann you are psychic...actually I was about to post that Marie's hair looks more red in the photo than in the painting. I don't know why that is so. I used red and yellow mixed in the brown for her highlights, but as I say ...the result, most likely due to my questionable photography skills, is it appeared more red here than I intended...or is ...so in the picture, it's a good deal browner. How I arrived at the colour? After awhile one can get a sense from the grade of the gray tones...the photos aren't strictly b/w, they are shades of grey as well. It can't be exact of course, but it can be close...one hopes. But rosieposie is correct as well . One reads everything and puts all that into the mix. In this regard, Tatiana's eyes are a real puzzler. I have read of them being " amber" and " light grey" and " dark grey," ...so which do you go with? I went with light grey in the sun light and dark grey in shadow. Thanks for the question!
