Bar colors question

Is there the type of choosing a color of bars - by default the bar has a down color if close lower than open.
I want to the option when down color is if close lower than previous bar close, not open of the current bar
And vice versa for up colors, respectively

The issue names no file, test, or entry point. Start by locating mplfinance's bar or candlestick color-selection logic and compare its current open/close rule with the requested previous-close rule. Done means an option for choosing the comparison basis, with tests covering both up and down colors.
