Need help to modify Volume indicator to show only up and down bar colors

Can someone help to modify the Better Volume Indicator colors to display only up & down bar colors?

At the same time displaying 2 moving averages like the one that appears in Hidden Gap Volume Indicator?
(the 2 MA are displaying in green and teal color in the HG indicator)


I have attached the 2 volume indicators.
Would appreciate if anyone can help on this, thanks!
