Fortunatelly I took my art supplies with me so I could play with colors already. I took Fabriano Artistico HP paper, which I cut into smaller pieces, because I knew I would do some sketches here. I read somewhere that the right side of the paper is the one with watermark. Unfortunatelly, when I was cutting the paper to smaller pieces I forgot to mark the right side. But FA paper has a specific texture on both sides, each one is different. I remembered how was the texure when I was painting the Vicia Cracca, and now I tried the other side (the "wrong" side) but I found it very good, maybe even better than the right side.
Because I don't have an actual living plant, I have only photos, so I work from the photos (I know, I shouldn't, but I see nothing wrong with painting from the photos. It's better to paint from the photos than don't paint at all).
For my first flower I chose the one with purple-reddish petals. I took another piece of paper, placed it next to the painting, and started mixing my colors. I love greens, but purples (or violets - I have no idea what is the difference in english), especially very deep purples are my favourite as well.
I laid down the first washes with mixes of Permanent Rose, Perylene Violet and Mauve.
