As with all UV2 dubbings, these have a mix of primary colors that have been enhanced with UV Florescence and UV Reflectence dyes.
We then blend these in with other fibers to achieve the over all base color while still giving it all the multi color property's of UV2.
Each dubbing will kick out a host of color spectrums.
Check them out in direct sunlight.
It is best to always use a pearl or silver Mylar under base or even basic white thread which will bounce any light back out of the pattern at a different wave length.

We have used a double dye process to give all our unique UV2 materials and flies the added UVF/UVR ultraviolet wave lengths.
We all know UV Florescence which is so common on everything from street signs to bass lures.
UV Reflectence is a spectrum of wave lengths humans can not perceive yet is extremely common in the animal and insect world. UVR allows mayflies to find mates, and bees to find flowers.
Many male birds and bugs have a strong natural UVR signature.
