_a._ The color of the upper body and wings determines the principal color classification of pigeons. In addition to principal color classification (see _b_(1) below), include the following classifications when applicable: (1) If any of the primary flights are white, the pigeon is classed as a “white flight.” Unless the flights are pure white the classification “white flight” is not made. (2) If all the coverts exhibit a light gray fringe on their outer edges, presenting a checkered appearance rather than a solid color, the pigeon is classed as “checkered.” (3) When a pigeon has white patches of feathers on its head, it is classed as “pied.” If these white patches extend to its body, it is classed as “splash.” (4) If a pigeon exhibits one or two white feathers about the eyes, it is classed as “tick.” _b._ Main color classifications for pigeons and their authorized abbreviations follow: (1) _Principal colors._ _Type_ _Abbreviation_ _Description_ Black (Blk) All feathers are black. Blue (B) All feathers are grayish blue, generally with two black bars on each wing. Silver (Sil) All feathers are deep grayish silver, generally with two red bars on each wing. Red (R) All feathers are a solid brownish red (often called chocolate). (2) _Checkers._ _Type_ _Abbreviation_ _Description_ Black Checker (Blk ch) Principal color black with dark gray or checker markings on rump and underpart of body. Dark checker (Dk ch) Similar to black checker but showing more distinct checker markings on the wing. Blue checker (B ch) Principally blue with checker markings on the body and wings. Red checker (R ch) Principally red with checker markings on the body and wings. Dun (Dun) Similar to silver except principal color is of a darker shade. Mealy (Mly) Similar to dun except that they do not have sharply defined red markings on the wings.
