Color Change Technology
NASA explored and pioneered early forms of sun-activated color for its space program. Del Sol combined science and sunshine to create its proprietary Spectrachrome® technology that makes all its products change colors for everyone under the sun!
Explore Del Sol's color change Lab in this video on Spectrachrome® technology.

Del Sol's Spectrachrome® inks are mixed on hotplate/stirrers in one of many steps of production.
The Magic that Makes Sunshine and Color Come to Life. NASA May Have Taken it to the Moon, but We're taking it to the World!
How it Works:
It's magic! Seriously, it's the magic of Del Sol's proprietary Spectrachrome® Technology, which harnesses the power of the sun through what chemists call a molecular excitation transition. In simpler terms, it means that Spectrachrome crystals reveal their hidden colors when exposed to sunlight. NASA invented it for their space program, and Del Sol enhanced it for everyone under the sun! It's not rocket science, but then again, maybe it is.
Why it's AWESOME!
Every time the sunshine touches your "whatever-you-took- home" from Del Sol, you'll feel like a million bucks as the party entertainer or the walking conversation piece. You'll only hear whistles and cheers as you demonstrate the coolest show 'n tell gift ever; and most importantly, you'll always be reminded of that incredible vacation under the sun when Del Sol first created fun, joy, smiles and memories for you.
Del Sol has since grown to be recognized as the leader in the industry for color-changing, retail-specialty products, and the only world-wide producer of Spectrachrome® crystal dyes. Our product line features the brightest and most vibrant colors of the rainbow. Simply add the sun's ultraviolet rays to our products and watch the Spectrachrome® colors magically appear!
Del Sol's color changing threads are used in embroidery of shirts, hats, and more.
Color Change Questions
What are the crystals made of?
The Spectrachrome® crystal is chemically engineered of organic materials.
How does it work?
The Spectrachrome® crystal reveals 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.
What wavelength causes the reaction?
Although each Spectrachrome® crystal operates at a slightly different wavelength, the optimal wavelength is 365 nanometers.
Does the molecule become larger when it is irradiated?
No, however it does take on a physical change.
How many colors are there?
To date, there are more than 30 colors. Many of these are quite similar to one another; hence, the usable range is narrowed to about 10. The Del Sol Spectrachrome® chemists have tested over 6,000 products.FAQ
