Porthole 6

A sophisticated gradient shader effect featuring diagonal parallel stripes that transition smoothly from deep purple on the left to warm beige/tan on the right. The composition uses a linear gradient as the base layer, flowing horizontally from #6c3086 (dark purple) to #decfa3 (light tan). Overlaid on this gradient is a sawtooth wave distortion effect with a frequency of 7.7, creating diagonal striped bands that appear to ripple and undulate across the canvas. The wave distortion has a strength of 2 and uses an angle range mapped between 70-110 degrees, controlled by an invisible circular mask positioned at coordinates (0.253, 0.552) with a radius of 0.85. This creates a subtle radial influence on the wave angle variation. The diagonal stripes maintain consistent spacing and create a sense of depth and movement, with the distortion effect giving the flat gradient a three-dimensional, folded appearance. The overall mood is modern and elegant, with smooth color transitions and a subtle sense of motion or flow. The effect uses LCH color space for the gradient, ensuring perceptually uniform color transitions.
