Lux Corallium - Fran Bull, c. 1990s

Lux Corallium by Fran Bull is an abstract work that uses color, sheen, and atmospheric layering to create something that appears to shimmer off the paper. Color plays the dominant role, with gold hues taking center stage across much of the composition. Bull adds depth through ethereal washes of coral, orange, teal, blue, and pale green, creating a surface that feels luminous, suspended, and almost aquatic. The work seems to glow from within, as though light is passing through layers of mineral, water, and organic matter.

The title, Lux Corallium, suggests a meeting of light and coral-like form. It behaves like a living surface: porous, radiant, and changeable. The colors bloom into one another in soft transitions, producing the feeling of something submerged, weathered, and slowly forming. Bull’s handling of pigment gives the work a sense of movement without relying on obvious line. The composition seems to drift, bleed, and expand through color alone.

The concentration of black paint complicates the work by injecting a sense of menace. Without it, the painting might read as purely beautiful or atmospheric. The black gives the image gravity. It interrupts the luminous field and adds a somber maturity, making the work feel less like decoration and more like a meditation on disturbance. Beauty is present, but it is not untouched. Something darker has entered the field and changed the terms of the image.

Within this concentration, the black appears to sit on top of the gold, while teal rests over the black, as though attempting to reclaim the distortion caused by its presence. This layering creates one of the most compelling tensions in the painting. The black does not fully disappear, but neither does it fully dominate. The surrounding colors respond to it, press against it, and at times seem to overtake it. The result is a visual struggle between obstruction and radiance.

What is especially telling is that Bull avoids blending these colors as much as possible in the areas of greatest tension. Instead, she presents them as distinct and somewhat incompatible materials. This sharply diverges from the rest of the painting, where colors blend and shift through gradients, washes, and gentle transitions. In the more luminous passages, color feels atmospheric and cooperative. In the darker passages, color becomes territorial. The surface becomes a field of negotiation.

On the right side of the image, the black reappears, though with a smaller presence. Even there, the teal surrounds it forcefully, bleeding over and around it in what feels like an attempt to purge, contain, or transform it. These repeated confrontations give the work its intellectual charge. Bull is not simply balancing colors for visual pleasure. She seems to be testing how materials behave when forced into proximity: what blends, what resists, what stains, and what survives.

Through this lens, Lux Corallium becomes a lively composition full of movement and action generated by color itself. Many abstract works explore separation and harmony, but Bull seems especially interested here in compatibility, or the lack of it. Space on the paper is finite, and the colors are left to stake their claims. Gold expands. Coral warms the surface. Teal cools and contains. Black interrupts. Each color carries its own force, and the painting gains energy from their unresolved coexistence.

The work is also notable because it does not fit neatly within Bull’s other abstract series. It shares the organic atmosphere of the Sophia works and the luminous mystery of some of her later abstractions, but it feels distinct in its method. Rather than relying on repeated motifs, secret alphabets, or clearly cellular structures, Bull lets the drama unfold through washes, overlays, and chromatic resistance. The painting feels exploratory, as though she is searching for new ways to push her abstraction through blending, separation, and material opposition.

Lux Corallium is both aesthetically seductive and intellectually rewarding. Its beauty is immediate, but its complexity reveals itself through sustained looking. Bull creates a world where color is not passive, but active: advancing, retreating, obscuring, and illuminating. The result is a radiant and unresolved work, one that shimmers with light while acknowledging the darker forces that complicate it.
