I experimented with this water lily painting on how to most effectively paint shapes that has only very subtle color variations and next to each other -- I tried to paint some petals one at a time, carefully model the roundness of them by adding deeper and deeper reds when I was painting each petal; some other petals are painted as one shape with slight warm/cool variations of reds, then crevice darks are added between petals after the underlying colors are dry. I tried both and wanted to find out how to avoid leaving a very harsh, dark edge at the border between two petals, which is the result of wetting an area then adding dark colors wet-in-wet. I find when I paint one petal at a time, it is easier to clean the edge of each petal buy running a damp stiff nylon brush along where the dark pigment accumulates, then blog the area slightly with tissue. When painting multiple petals at once, the petals painted at the same time have better connections and looks more natural, yet the edge between sections painted at one time and another always looks quite harsh. I am still struggling to find a good method and make the connection of areas painted sequentially more natural... If you have some good tips, please share with me, my friends!
