This painting features muted tones of green and yellow, with subtle layers of light and color emerging from the center. The soft, diffused hues and vertical structure evoke a sense of translucency, reminiscent of stained glass windows. The central glow, framed by darker shades of green, draws the viewer in, as if light is filtering through from behind the surface. The soft transitions between colors and the misty quality of the composition suggest a meditative, almost musical rhythm.

The comparison to stained glass windows is especially relevant, given the title's reference to "Vitrales," which means stained glass in Spanish. The interplay of light and shadow, with hints of golden yellow illuminating the central portion of the painting, creates a similar effect to how light passes through colored glass. This treatment recalls the luminous quality found in the works of Mark Rothko, particularly his later pieces, where glowing fields of color seem to emit their own light. However, while Rothko’s color fields are expansive and immersive, this painting focuses the viewer’s attention on a central source of illumination, contained within a vertical frame, giving it a more intimate feel.

In the context of the artist comparing his paintings to music, this piece resonates like a slow, atmospheric melody. The way the colors blend softly into one another feels like notes gently weaving together in harmony. The dominant yellows and greens play off each other like contrasting chords, while the central glowing area acts as a crescendo, drawing attention to the heart of the composition. The rhythm and flow of the painting mirror the fluid, dynamic nature of music, where subtle shifts create a larger emotional impact. This recalls the works of Paul Klee, who often compared his art to musical compositions, particularly in his use of rhythm and balance between tones.

What sets this painting apart from others is its ethereal quality—the colors are not sharply defined but rather dissolve into one another, creating a sense of depth and luminosity. Compared to the harder edges of traditional stained glass, the painting feels softer and more introspective, inviting the viewer to contemplate the nuances of light and shadow. This diffused light effect also shares a kinship with J.M.W. Turner’s late works, where light and atmosphere become the dominant forces, dissolving form into pure emotion. The relationship between light and darkness, much like in a musical composition, provides contrast and balance, enhancing the painting’s contemplative mood.
