Please be aware that photographic computer images of bead colors are tricky things; varying according to lighting, the whims of the camera, and your individual computer monitor display. Photo colors can appear dramatically different when viewed on different computer monitors. (High def monitors intensify most colors, mutate others, and can even turn regular colors neon bright.)
Even in person, beads can be little chameleons, changing colors dramatically when viewed in different lights. When you receive your beads, you should look at the colors in natural sunlight as well as by indoor light. Beads can change from blue to purple, clear to yellow, gray to amethyst, etc.
