The petals of this plastic flower change color when placed in the sun. It uses Gluminous photochromic powder (orange) mixed into InstaMorph moldable plastic to achieve the effect. It starts out a light yellow in the shade and transitions to a deep orange/red in the sun.
“Although I never worked with photochromic powders before, the speed and boldness of the color shifts was really amazing!”
This is because Gluminous powders are almost 2x smaller in diameter than other brands, meaning more surface area by weight and quicker transitions when placed in the sun.
