Absolutely. Studies show cool blues and greens increase focus, while warm reds can spike urgency. Try a gradient that starts with a calm teal, blending into a subtle amber—this keeps users calm yet motivated. Track time on task and completion rates before and after the change. If you see a 3‑5% uptick, you’ve hit a sweet spot. Keep the colors consistent, adjust only one variable at a time, and iterate fast. That’s the data‑driven way to lift productivity.
