Description
How to add moving average on Volume Panel (panel = 1) if volume is set to True.
I have plotted mav(9,26) in Panel 0 using 'mav' function
If I edit and enter Volume = False and add Volume in Panel 1 using addplot funtion. Color of the volume candles becomes solid blue irrespective of the color of the candle in Panel '0'
EDIT:
here is a part of the code
#chart style parameters and plotting function
mc = mpf.make_marketcolors(up='g',down='r',
edge='inherit',
wick='black',
volume='in',
ohlc='i')
s = mpf.make_mpf_style(marketcolors=mc)
apc = [mpf.make_addplot(stck['rsi'].iloc[170:],panel=2,color='g',type = 'line',ylabel='RSI'),
mpf.make_addplot(stck['rsi_overbought'].iloc[170:], panel=2,color='blue',type = 'line',linestyle='-.',secondary_y=False),
mpf.make_addplot(stck['rsi_oversold'].iloc[170:], panel=2,color='red',type = 'line',linestyle='-.', secondary_y=False),
mpf.make_addplot(stck['Volume'].iloc[170:],panel =1,type = 'bar', mav = 10,color = 'in')]
mpf.plot(stck.iloc[170:], type='candlestick', volume=False,title = ticker, tight_layout=True, hlines=ml_results,
mav=(9,26), style = s, returnfig=True,addplot = apc)

Research direction
Start from the make_addplot call for the volume series and the mpf.plot invocation shown in the issue, focusing on panel 1 with volume=False. Trace how the volume bar colors and moving-average option are handled for an addplot, then verify that the volume panel displays the requested moving average and preserves the intended candle colors.
