This is not a minimalist painting but is still a kind of "Op Art". It is a photograph of the side of a shipping container taken through a window, creating painterly "imperfections". It is not so much a piece of art as it is an aesthetic phenomenon that emerges when illuminated by sunlight, creating three shades of orange color from light and shadow--a corrugation of color.
Placing a sheet of orange corrugated steel in a gallery can be conceptual but it is not art per se, as it requires a specific place, orientations, and lighting conditions. It certainly can inspire art, and many artists glean ideas like this from things seen in everyday life, then recreate them as a form of art for the purpose of informing perception.
Using a musical metaphor, bar lines do something similar: taking a flow of time (one "color") and delimiting it with bar lines.
Gerhard Richter did something like this with Strips, where a set of stacked color swatches could be stretched horizontally or vertically into infinity--or whatever the limits are in physical (size of the wall) space, and digital limits (the file size).

1050. Perception is a concerted effort: artists tend to see differently, as do people in law enforcement, or even people not particularly engaged with the world. Reverie is something anyone can participate in, and can lead to higher baseline of awareness. But it doesn't happen automatically.
0713. Digital art becomes less digital when it is fixed in an analog medium. In other ways the digital realm is merely a provisional temporary state to affect a certain experience. The primary difference between digital and analog entities is how they are experienced cognitively, especially with vision: digital art is a backlit phenomenon, whereas painting, prints, and sculpture reflect ambient light to the eyes, affecting color perception.
