Three highly tech-looking color combinations

Quick answer：

Color combinations that give off a strong sense of technology often include neon, metallic, and monochromatic shades. Neon colors, like bright blues or greens, evoke a futuristic feel. Metallic tones, such as silver or gold, provide a sleek, modern appearance. Monochromatic palettes, using different shades of a single color, can also create a high-tech aesthetic by focusing on depth and contrast.
