Creating Volum inddictor with volume bars in 3 colours

I think about very simple Volume indicator for TradingView with 3 colour bars?: For Standard Volume it would be 3 bars: bullish, bearish and third pink volume bar lower than n previous volume bars. Can someone help me with that?

Hi

You might want to use the barcolor function

Example:

barcolor(bullish_condition ? color.green : bearish_condition ? color.red : volume_lower_than_n_previous_bars ? color.pink : color.na, title="Bar Color")
