Coloring column's chart in TradingView, positive and negative values

Question

I'm using economic data in TradingView in column type chart. The values can be positive and negative (differently of prices values that can not be negative).

I need a Pine Editor script for to color bars based on positive and negative values.

I tried the following code, but it did not work.

//@version=5
indicator("Positive/Negative Column Coloring", overlay=true)

// Determine the color of the columns based on positive and negative values
columnColor = close >= 0 ? color.green : color.red

// Plotting the columns with the appropriate color
plotbar(close, color=columnColor)

// Plotting the closing price as a line
plot(close, title="Close", color=color.blue)

Thank you.
