John Lennart Roo’s artistic style is a captivating blend of jump-off-the-canvas realism and a muted, dreamy style in what he calls “The Mist” series. With a lifetime of art, illustration, and graphic design experience under his belt, he began prolifically creating and putting his work out into the world just a few years ago after retiring in Napa Valley.
His Mist Series is inspired by the unique wine country viewpoint of quiet, early morning, fog-filled walks through pastoral landscapes. The subdued backdrops, contrasted with realistic overlays, invite viewers to delve into their thoughts and emotions, fostering contemplation.
“I’m looking to give the viewer a moment where they picture themselves having just walked past the No Trespassing sign,” Roos explained.
The series has deeply resonated with art lovers. “I’ve been doing the misty series paintings over the last year and a half; I’m working on my sixth right now,” Roos shared.
He is represented by and teaches at the Jessel Gallery, a Napa Valley landmark where many local and national artists have honed their skills and left their mark on the region with the guiding hand and spirit of founder, artist, and local legend Jessel Miller.
Roos began his graphic and illustration career after receiving formal art training from the Chicago Academy of Fine Art. He then focused on graphics and illustration, working in those industries for 40 years. His background in educational children’s books and cartoon illustration shines through in some of his work, which brings a refreshing tongue-in-cheek element to his portfolio.
Take his delightful and whimsical ostrich in Monet’s lily pond, “Hey Claude, OK to Swim?” Another work shows a carrot clown in a shoe, expertly painted with details like a wry carrot smile for the perceptive viewer. These pieces highlight the genesis of his realistic point of view, which came to fruition before he used it as a juxtaposition in his misty paintings.
Some of his other works include Brat Dog and Lokinvelder. The Brat Dog series features charming paintings of lovable but naughty four-legged friends caught red-handed in suspicious situations. One series shows individual sweet pups sitting in a corner as various scenes of destruction surround them. The Lokinvelder paintings highlight Napa Valley’s black-and-white cows—Belted Galloway cattle, but what locals call Oreo cows—striking images of these iconic animals.
Roos displayed his work at the 2025 Mustard Celebration, an art event celebrating local artists and the art they create. It coincides with the time of year when the valley’s bright yellow mustard flowers are in bloom and cover the valley floor for a dramatic backdrop to the celebration. The prestigious event is held at the Napa Valley Culinary Institute of America (CIA), a renowned venue for art exhibitions. In 2009, Roos’s Oreo cow painting, Night Light, won 2nd place overall.
