Pixel art for a dark 2D side-scrolling action game set in China's Three Kingdoms era, around 200 AD. Muted low-saturation palette of dark blues, slate greys and earth browns with very small dull red accents. Large crisp pixels, flat shading, no characters, no people, no text, no UI. Middle-distance scenery seen from the side, filling only the lower half and running the full width: the outer colonnade of a Han dynasty palace at night, tall red pillars, deep eaves, bronze braziers, carved railings. Dim and ominous, seen through haze. The background is one plain solid magenta colour (#ff00ff) with nothing else in it, for chroma keying.
