The title Flash resonates with several visual elements within the painting: the sudden, reflective glint of light off the fish's scales as they circle the light from above, the rapid, synchronized movement of the school, and the explosive, radiant burst of light in the center. It evokes the transient yet impactful moments found within the underwater world, highlighting the interplay of light and life beneath the surface.

The painting evokes a sense of wonder as the fish swim around a luminous "halo" filtering through the depths of the water.
