The light is interior light. You might notice that it’s warm on the top of the leaves. Nevertheless, the shadows are transparent. Outdoor light might have been coming into the room too. I painted this so long ago that I don’t remember.
There were several bouquets that I set up on the same pale blue cloth. Lemons form a counterpoint in them, their yellow providing chromatic opposition to the violet of the lilacs. I remember that I liked describing the forms of the lemons with strong outlines. With these I was particularly pleased because they look solid.
You can see some of the warmth of the interior light in the blue cloth too. A yellowish cast reflects off the blue in places.
I felt like these flowers have almost a personality. They seem cheerful. Plural. Definitely an ensemble of happy lilacs. The same bush that produced these lilacs finished blooming only a day or so ago. So many years later!
