Shade of disc color may vary. For example, yellow can be a mustard yellow or a bright yellow. Discs are two-toned, second tone will vary.
Axiom says of the Proxy:
"The Proxy shares the Envy mold’s core, lending the same low-profile feel and solid grip, along with a short wing width and wide flight plate diameter for superior glide. The Proxy sets itself apart from the Envy with a remarkably straight forward-fading finish. A bit of high-speed turn potential allows the Proxy’s lines to be manipulated over a broad range of power, and helps less powerful throwers achieve straight putter drives."
