Grateful for the plain old panes of window glass, I shudder to think of life in buildings without windows.
I love watercolor for many reasons but one, for sure, is its transparency. (Not all watercolor is transparent but it's the main game and what I've used for over half-a-century.)
At best watercolor is clean, clean, illuminated. Like window panes, watercolor is transparent, which matters because it lets the light shine through.
To send light into the darkness of men's hearts - such is the duty of the artist. —Robert Schumann
