digiTats

In the Red Rising Saga, digiTats debut as the signature neural interfaces of the Blues, the lowColor caste of shipwrights and technicians, manifesting as glowing, snaking tattoos across their bald heads, spidery hands, scalps, temples, necks, and forearms. These digital tattoos pulse in cerulean, azure, and silver hues when syncing with ship computers, consoles, and neural links, dynamically displaying complex math and physics equations, trident-like Sigils, holographic projections, and digital commands essential for interstellar navigation and engineering. Though introduced prominently in Golden Son, digiTats underscore the Blues' indispensable yet oppressed role in Society's machinery, evolving implicitly as symbols of technological caste hierarchy across the series without major alterations in later books.
