Mask is a Dye Marking that color's the waja's muzzle and places a streak of color between its eyes. On most breeds the marking also lines the wajas eyes and places two dots above them. You can add this marking to your waja by use of a Dye Mask.
All examples feature wajas with the marking in FF0000 (pure red). However, this marking can come in any Hex Color as well as rainbow (simply put the word "RAINBOW" in the hex field) and chrome (simply put the word "chrome" in the hex field).
