Smokey Logo 4

A dramatic shader effect depicting a glowing archway or tunnel opening against a deep dark background. The composition features a symmetrical arched structure with warm golden-orange illumination emanating from within the opening. The arch itself appears as a dark silhouette, creating strong contrast against the luminous interior. Billowing smoke effects in warm amber and orange tones (#ffb347, #ff6a00) flow from the center of the arch, creating a sense of heat and movement. Secondary darker smoke layers in brown (#3d2219) and deep blue (#0b132e) add depth and atmospheric complexity. The smoke dissipates outward with a soft, organic quality, suggesting turbulent air currents. The overall mood is mysterious and ominous, with the warm glow suggesting either fire or otherworldly light. The background is nearly black (#0d0817), making the glowing arch the clear focal point. The effect combines volumetric smoke simulation with directional particle emission, creating a three-dimensional sense of depth and atmospheric perspective.
