This AFL detects Boring/Base candle if its body (open-close) is less than 50% of candle size (high-low) and changes its color to blue. This is very useful in price action trading.

body (open-close) is less than 50% of candle size (high-low)

normalCandle = (Open < Close);
baseCandle = abs(Open-Close)/abs(High-Close) < 0.5;
BarColor = Iif( baseCandle, colorBlue, IIf(normalCandle, colorGreen, colorRed) );
// set color
Plot( Close, "Price", BarColor, styleCandle );
//PlotOHLC(open, high, low, close, "This is base candle", BarColor, styleCandle);

minor correction.

normalCandle = (Open < Close);
baseCandle = abs(Open-Close)/abs(High-Low) < 0.5;
BarColor = Iif( baseCandle, colorBlue, IIf(normalCandle, colorGreen, colorRed) );
// set color
Plot( Close, "Price", BarColor, styleCandle );
