How to Color Code Volume Bars Based on Thresholds in Indie Script?

Question

I’m making a volume indicator in TakeProfit's Indie and I want to color the volume bars based on different thresholds.

For example:

• ≥ 200,000 → Red

• ≥ 100,000 → Light Blue

• ≥ 50,000 → Dark Blue

• < 50,000 → Gray (default)

I tried using plot.Histogram() but I got an error about missing arguments.

# indie:lang_version = 5
from indie import indicator, color, plot

@indicator('Colored Volume Bars', overlay_main_pane=False)
@plot.histogram('Volume')
def Main(self):
    vol = self.volume[0]
    vol_color = color.GRAY(0.5)  # Default color to ensure initialization

    if vol >= 200000:
        vol_color = color.RED
    elif vol >= 100000:
        vol_color = color.BLUE(0.5)  # Light blue
    elif vol >= 50000:
        vol_color = color.BLUE  # Dark blue

    return vol, plot.Histogram(color=vol_color)

Error: 17:16 could not find function definition that matches indie.plot.Histogram call, reason: required arg value is not provided for param value

How do I color code a volume histogram in Indie?

UPD: find solution

return plot.Histogram(value=vol, color=vol_color)
