Generally speaking this is the case, however some petitioners have been granted specific livery colours and these may then be displayed as the wreath (or torse as it is sometimes called). Cyril Woods of Slane, Baron of Slane chose to have his livery colours (unusually three colours; or, sable, and gules) so displayed in the exemplification of his arms on his letters patent.
