What if your house changed color with the seasons? This ‘climate-responsive’ paint could make it happen

Joe Doucet developed climate-responsive paint that changes color seasonally to help temperate-zone homes regulate temperature in 2025.
He created the paint in response to rising temperatures, increased air conditioning use, and uncertain clean energy policies under Trump.
Doucet’s thermochromic pigment turns dark below 77°F to warm interiors in winter and lightens above 77°F to cool them in summer.
Testing showed black-painted models were 7°F warmer in winter and white ones 12°F cooler in summer, projecting 15%–30% energy savings per household.
If widely adopted over the next five to 10 years, the paint could significantly reduce building energy use and support climate adaptation in temperate regions.
