Undertones 9

A vertical striped shader effect displaying a smooth gradient transition from dark to bright orange-red tones. The composition features approximately 12 evenly-spaced vertical lines or bars that divide the canvas, creating a venetian blind or louvered appearance. The leftmost bars are nearly black with minimal visible color, gradually transitioning through dark brown and deep red tones in the center-left bars. The middle section shows the most vibrant orange-red coloration (#ff3312 and #ff5b38 range), appearing warm and luminous. The rightmost bars fade back toward darker tones with some black vignetting at the edges. The effect creates a sense of depth and motion, as if viewing a glowing heat source through vertical slats. A subtle fluted glass refraction effect creates fine horizontal wave patterns across the bars, adding texture and optical distortion. The overall atmosphere is warm, energetic, and slightly industrial. Film grain adds a subtle noise texture throughout. The lighting appears to come from behind or within the bars, creating a backlit glow effect with chromatic color flow that emphasizes the orange-red spectrum.
