The flag of Bhutan splits the field on the diagonal — golden-yellow upper triangle over saffron-orange lower triangle — crossed by the white Druk, the thunder dragon, clutching jewels in its claws. Standardised in its modern form by 1969, it is the heraldry of Drukpa Buddhism: marigold for the secular authority of the king, saffron for the spiritual tradition, and the roaring dragon for the storms that give the Land of the Thunder Dragon its name.

This design system renders that vexillology in flat, saturated heraldic fields — no gradients, no pastels — anchored by a bold saffron-orange ground, with white reserved strictly for the dragon emblem.
