For example, if the color range is defined as White to Black, and the value range is defined from 0 to 2, GradientColor will return an RGB color number representing White for the value of 0, Gray for the value of 1, and Black for the value of 2. White will be returned for all values < 0, and Black for all values > 2.
==== Usage ====<syntaxhighlight>GradientColor(Value,Min,Max,StartColor,EndColor)</syntaxhighlight>  Where:
Where: [['''Value]] ''' – the specified numerical expression.
[[:'''Min]] ''' – the minimum value of the value range; if . If '''Value=Min''' is equal to or lower than the minimum value, the '''StartColor ''' is returnereturned.
[[:'''Max]] ''' – the maximum value of the value range; if . If '''Value=Max''' is equal to or greater than the maximum value, the '''EndColor ''' is returned.
[[:'''StartColor]] ''' – the starting color of the gradient color range.
[[:'''EndColor]] ''' – the ending color of the gradient color range .
==== Example ====
Plot an ADX indicator in Gradient Color, where Magenta gradually changes into White for the indicator values from 5 to 50:
<syntaxhighlight>Variable: ADXValue(0);
 
ADXValue = ADX(14);
Plot1(ADXValue, "ADXValue");
<syntaxhighlight>Variable:ADXValue(0);ADXValue=ADX(14);Plot1(ADXValue,"ADXValue");SetPlotColor (1,GradientColor (ADXValue,5,50, Magenta,White));</syntaxhighlight>
