Changing discount prices from red to green boosted ARPU by 2.54%
Red screams "sale urgency" but often spikes anxiety in shoppers.
We flipped it to green on product detail pages sitewide for a women's activewear brand.
Hypothesis: Green signals positivity and savings, easing decisions without the red alarm vibe.
Results across all users:
ARPU: 2.54% (from €3.24 to €3.33)
AOV: 2.20%
Conversion rate: 0.34%
Statistically significant, with returning users seeing a whopping 5.58% ARPU lift.
Mobile held strong at 2.78% ARPU, while desktop jumped 4.36%.
Why it crushed:
Color psychology nails it: Green evokes trust, approval, and even eco-vibes, aligning with value-driven buyers.
Red triggers loss aversion (grab it now!), but green promotes relaxed spending, leading to bigger carts.
No more decision stress; shoppers felt the win, not the pressure.
Key takeaway: Ditch the red "fire sale" trope. Subtle color shifts can unlock hidden revenue without overhauling your site.
Test everything, even the "tiny" stuff.
