[Ants-double]

I Changed the color code .but it will work show a Single Color. var guiControls = new function () { this.model = 'bonsai'; this.steps = 256.0; this.alphaCorrection = 1; this.color1 = "#000000"; this.stepPos1 = 0.0; this.color2 = "#ff0077"; this.stepPos2 = 0.22; this.color3 = "#3f7210"; this.stepPos3 = 0.3; //this.color4 = "#FFFAFA"; //this.stepPos4 = 0.65; //this.color5 = "#FF1493"; //this.stepPos5 = 0.85; //this.color6 = "#FFff00"; //this.stepPos6 = 1.0;

};
