The colours of by far the greatest frequency of occurrence are red, white, and blue; yellow also is not uncommon; orange is only found once, in Fig. 249, where it has a special significance, since this is the flag of the Orange Free State. Green occurs sparingly. Italy (Fig. 197) is perhaps the best known example. We also find it in the Brazilian flag (Fig. 169), the Mexican (Fig. 172), in the Hungarian tricolor (Fig. 214), and in Figs. 199, 201, 209, the flags {24} of smaller German States, but it is more especially associated with Mohammedan States, as in Figs. 58, 63, 64, 235. Black is found but seldom, but as heraldic requirements necessitate that it should be combined either with white or yellow, it is, when seen, exceptionally brilliant and effective. We see it, for example, in the Royal Standard of Spain, (Fig. 194), in Figs. 207 and 208, flags of the German Empire, in Fig. 226, the Imperial Standard of Russia, and in Fig. 236, the brilliant tricolor of the Belgians.[15] In orthodox flags anything of the nature of an inscription is very seldom seen. We find a reference to order and progress on the Brazilian flag (Fig. 169), while the Turkish Imperial Standard (Fig. 238) bears on its scarlet folds the monogram of the Sultan; but these exceptions are rare.[16] We have seen that, on the contrary, on the flags of insurgents and malcontents the inscription often counts for much. On the alteration of the style in the year 1752 this necessary change was made the subject of much ignorant reproach of the government of the day, and was used as a weapon of party warfare. An amusing instance of this feeling occurs in the first plate of Hogarth's election series, where a malcontent, or perhaps only a man anxious to earn a shilling, carries a big flag inscribed, "Give us back our eleven days." The flags of the Covenanters often bore mottoes or texts. Fig. 34 is a curious example: the flag hoisted by the crew of H.M.S. _Niger_ when they opposed the mutineers in 1797 at Sheerness. It is preserved in the Royal United Service Museum. It is, as we have seen, ordinarily the insubordinate and rebellious who break out into inscriptions of more or less piety or pungency, but we may conclude that the loyal sailors fighting under the royal flag adopted this device in addition as one means the more of fighting the rebels with their own weapons.
