This is the code to plot red, green bar colours. Scroll down to the code plot as below and comment out as I have and place the red/green bar colour plot code in there. In future you can uncomment the original syntax and comment out the plot green/red bars syntax to have the original back.
Plot( Close, "Price", IIf( Close > Open, colorGreen, colorRed ), styleBar | styleThick );
// bar_kol = IIf(impulse_UP, colorBlue, IIf(impulse_Down, colorRed,
// Plot(C, "Close", bar_kol, styleBar);
