Here's the question:
What are some of the reasons it's not on topic? Is it because of the nature of the specified hands-on application (painting a wall for home improvement, not art)?
Would it make a difference if the question were about:
- LED bulbs interacting with painted pieces in general?
- How to best light your artwork?
- How to best choose a palette for your sculpture that's suited for a LED bulb's spectrum?
- A straight color theory question about LED interaction with pigment-based palettes?
With the ways that this question is off-topic, can we create guidance for how to make good, on-topic color-theory or color-selection questions?
Here's an example of a question that was very specific about selecting colors, down to the brand and what colors they needed to be matched to: What Faber-Castell Polychromos color codes do I need to paint this?
Purely a color theory question: What is a split primary palette?
Question about how surrounding color affects appearance: Dim lighting with colored pencils
