Any way to change volume bar colors by comparing consecutive volumes, not by prices

Hello.

Are there any way to change volume bar colors by comparing consecutive volumes, not by prices?

If today's volume >= yesterday volume, GREEN volume bar
If today's volume < yesterday volume, RED volume bar

Thanks.

Start by tracing mplfinance's existing volume-bar coloring behavior and how it compares prices; the issue does not name a file or test. Done means consecutive volumes are compared so bars are green when today's volume is at least yesterday's and red when it is lower.
