I decided to "take a chance" with this painting. instead of leaving the irises blue or painting them white, I opted for a reddish hue for the flowers. This gave a nice contrast/complementary hue to play off the green leaves. I'm pleased with the results. The finished painting, which is on stretched canvas, measures 18 x 24 inches (45.72 x 60.96 cm.)
Next photos below are some details from this painting. First is this cat's face--but especially his eyes, which are a luminous minty green.
Next photo shows portion of cat's front leg and some markings.
Last two photos here show a couple of the irises and the layering of first blue, then lavender. And then the reddish tone over top of those other colors.
