Colors are a measurable variable in a productivity experiment. A pastel backdrop tends to lower heart rate and cortisol, which translates into steadier focus and fewer errors. If you track time on task and error rate, you’ll likely see a small but statistically significant improvement. The key is to keep the variable isolated and control for lighting, task type, and individual preference. In short, yes—mood‑inducing colors can tilt the numbers in your favor.

Got it—steady light, consistent conditions, and a clear control group. When you run the test, log baseline productivity first, then swap in the pastel walls and keep everything else identical. Afterward compare the metrics; if the lavender or sea‑foam gives a higher median focus score or fewer task switches, you’ve got data that color can influence output. Keep the numbers front and center—no theatrics, just results. Good luck, and let me know what the stats reveal.
