This is a CLYW 2nd Generation Peak Test Color. It is a Gray to Baby Blue "color changing" with Orange Splash. The base color was supposed to be baby blue, buy came out in a muted Dove Gray which changes to Baby Blue from certain angles. Note the front half of the yoyo looks baby clue with the back half appearing more of a gray. This is not the case, but it is a great example of the illusion of the color change by certain angles. This was a really fantastic colorway, but accidental, and not something that could be requested or reproduced for a large run, so it never was.
