Green like emerald under a golden grating? shower curtain

Traces and green curves with alterations of shades that may seem emerald, with lines stained in yellow and gold colours that simulate splices. The colours of the lines around the squares can cause a perception of gold metallic ribbons, or some sort of grid over green. The green of the squares change from a dark shade at the top to the lightest at the bottom, this effect added to the contrast of the lines can cause the illusion that the squares are a bulky cloth trapped in a grid or mesh; depending on the position you observe, ambient lighting or personal perception.
