    // draws bottom left curve, the pretty lilac colored one
    for (x1 = 0; x1 < width; x1++) {
        x1 += 5;
        y2 += 5;

        // color lilac
        stroke(165, 125, 235);

        // draws curve

    // draws sunset-colored curve on right side of screen
    for (x1 = 0; x1 < width; x1++) {
        x1 = x1 + 4;
        y2 += 5;

        // draws sunset-color
        stroke(244, 66, 0);

        // draws curve
        line(x1, y1, width, y2 - 75);
    } 

    // draws maroon-colored lines in middle of screen
    for (var i = 30; i < width; i += 10) {
        i += 8;

        // color maroon
        stroke(130, 9, 41);

        // draws curve
        line(width - i, height, i * .25, 0);
    }

}

Was able to create several curved lines, including using the sin function to draw a sin curve in blue. Able to draw the bottom left and the right curves as, well, curves, and the center cross of lines in maroon.
