Deep navy base — feels like premium tech authority. Blue-family gradients. Professional, trusted, modern.
Dark eggplant base — violet/magenta/gold energy. Feels mystical, conscious, artistic. Perfect for "Tech Mystic" brand identity.
Background shifts from deep indigo → navy-teal → plum-purple as you scroll. Every section feels like entering a new space. Most dynamic/editorial of the three.
Bonus option — deep midnight blue with animated dot field. Clean, systematic. Good for technical/data-heavy sections.
