COLOR CHANGE MAGIC It's magic! Seriously, it's the magic of Del Sol's proprietary Spectrachrome® Technology, which harnesses the power of the sun through what our chemists call a molecular excitation transition. In simpler terms, it means that Spectrachrome crystals reveal their hidden colors when exposed to sunlight. NASA explored color-change technology for its space program, specifically for the transitional lenses on their astronauts’ space helmets, and Del Sol enhanced it for everyone under the sun! It's not rocket science, but then again, maybe it is.

WHY IT'S AMAZING! Every time the sun paints your Del Sol product with vibrant colors, you'll burst into a great big grin. It’s the coolest show 'n tell gift ever and, most importantly, you'll always be reminded of that vacation under the sun when Del Sol first created fun, joy, smiles and memories for you.

Del Sol has grown to become the world leader in color-changing clothing and accessories, and the only producer of Spectrachrome® crystal dyes. Our product collections feature the brightest, most vibrant colors of the rainbow. Simply add the sun's UV rays to Del Sol products and watch the Spectrachrome® colors magically appear!

WHAT ARE THE CRYSTALS MADE OF? The Spectrachrome® crystal is chemically engineered using all-organic materials.

HOW DOES IT WORK? Our Spectrachrome® crystals reveal color upon irradiation by ultraviolet waves; i.e., sunlight. When a flower blooms, the result is the exposure of the inherent color of the flower. A Spectrachrome® crystal is similar in that an energy-shift occurs causing the color of the dye to become visible to the human eye. The shifting or "twisting" of the dye is referred to as a molecular excitation transition. The dye does not actually "change" color; rather, it becomes visible to the human eye. Research shows that some animals; e.g., certain species of bats, can actually see the color of a Spectrachrome® crystal in its inactive state.

DOES THE MOLECULE BECOME LARGER WHEN IT IS IRRADIATED? No, however it does take on a physical change.

HOW MANY COLORS ARE THERE? Del Sol products feature the brightest, most vibrant colors within a vast color palette of more than 300 color varieties. Since 1994, Del Sol’s panel of chemists from around the world have tested more than 300,000 color-changing product variations, which naturally fuels our ongoing research and development efforts for even more color-changing creations to come.
