A long-standing heraldic tradition has been to avoid repeating the names of tinctures multiple times in any given blazon. If it is possible to mention multiple charges of the same tincture at once, followed by the name of the tincture, then this problem is avoided; but when it is impossible to combine elements of the same tincture in this manner, more creative descriptions may be used. For example, instead of "gules, on a fess or between three chess-rooks argent, a lion passant gules, armed and langued argent", one might say, "gules, on a fess or between three chess-rooks argent, a lion passant "of the field", armed and langued "of the third"." Similar phrases include "of the last" and "of the like". Alternately, descriptions such as "gold" and "silver" might be substituted for "or" and "argent" on a subsequent occurrence. Another rule of blazon relating to tinctures suggests the placing of a comma after each occurrence of a tincture.
