The next element that claims mention is Colour. In this domain the most striking contrasts are black and white. In ancient Greece, a common name for rivers was MELAS, or Black-water; one of which, that which flows into the Malaic Gulf, has translated itself into modern Greek as MAURO-NERO, μαûρο in the popular dialect having supplanted the classical μἐλας; and νἐρο, as old, no doubt, as Nereus and the Nereids, having come into its pre-Homeric rights and driven out the usurping ὕδωρ. In the Scottish Highlands, _dubh_, _black_ or _dark_, plays, as might be expected, a great figure in topographical nomenclature; of this let BENMUIC DUBH, or the _mount of the black sow_, familiar to many a Braemar deer-stalker, serve as an example; while CAIRNGORM, the cradle of many a golden-gleaming gem, stands with its dark blue (_gorm_) cap immediately opposite, and recalls to the classical fancy its etymological congeners in the CYANEAN rocks, so famous in early Greek fable. Of the contrasted epithet _white_, LEUCADIA (λευκός), where the poetess Sappho is famed to have made her erotic leap, is a familiar example. In the Highlands, _ban_ (fair), or _geal_ (white), is much less familiar in topographical nomenclature than _dubh_; BUIDHE, on the other hand (yellow), corresponding to the ξανθός of the Greeks, is extremely common, as in LOCHBUIE at the south-east corner of Mull, one of the few remaining scattered links of the possessions of the Macleans, once so mighty and latterly so foolish, in those parts. Among other colours, _glas_ (gray) is very common; so is _dearg_ (red), from the colour of the rock, as in one of those splendid peaks that shoot up behind the slate quarries at the west end of Glencoe. _Breac_, also (spotted or brindled), is by no means uncommon, as in BEN VRACKIE, prominent behind Pitlochrie, in Perthshire, in which word the initial _b_ has been softened into a _v_ by the law of aspiration peculiar to the Celtic languages.
