"Drift of Mineral Light" continues an investigating blue not only as a color, but as a behavior—a responsive system that changes with light, material, distance, and scale. I treat blue as an active field rather than a passive surface: it can absorb, recede, vibrate, soften edges, or sharpen contrast depending on how it is built and where it is encountered. The work is fundamentally empirical: I observe how blue shifts under warm vs. cool light, diffuse daylight vs. directional spots, and how it reads up close versus in peripheral vision at 3–8 meters.
