His approach shifted from the dark tones of the Hague School toward a lighter, more ethereal style. He often used thin layers of oil paint to create a translucent effect, particularly in his watercolours and river scenes like Gezicht op Hattem. Voerman was fascinated by the way light interacts with moisture in the air. His paintings of cows, such as Grazende koeien in een weiland, are less about the animals themselves and more about the space and air surrounding them. He avoided heavy textures to keep the focus on clarity and pale colours.

Modern collectors appreciate the calm and stillness found in Voerman's work. His compositions are often minimalist, with low horizons that give prominence to expansive skies. Works like La France-rozen in twee glazen show his ability to handle delicate subjects with precision. These prints offer a sense of order and quietude. They fit well in contemporary interiors because they provide a window into a world of soft light and open space without being overly sentimental.
