{{DISPLAYTITLE:_RGBA32}}
The [[_RGBA32]] function returns the 32-bit ''RGBA'' color value with the specified red, green, blue and alpha component intensities.


{{PageSyntax}}
: {{Parameter|color32value~&}} = [[_RGBA32]]({{Parameter|red&}}, {{Parameter|green&}}, {{Parameter|blue&}}, {{Parameter|alpha&}})


{{PageDescription}}
* The value returned is a 32-bit [[_UNSIGNED]] [[LONG]] color value. 
* '''Return variable types must be [[_UNSIGNED]] [[LONG]] or resulting color may lose the [[_BLUE]] value.'''
* {{Parameter|red&}} specifies the red component intensity from 0 to 255.
* {{Parameter|green&}} specifies the green component intensity from 0 to 255.
* {{Parameter|blue&}} specifies the blue component intensity from 0 to 255.
* {{Parameter|alpha&}} specifies the [[_ALPHA|''alpha'']] component transparency value from 0 (fully transparent) to 255 (opaque).
* Alpha or intensity values outside of the valid range of 0 to 255 are clipped.
* Returns [[LONG]] 32-bit hexadecimal values from '''&H00{{text|00|red}}{{text|00|green}}{{text|00|blue}}''' to '''&HFF{{text|FF|red}}{{text|FF|green}}{{text|FF|blue}}''' with varying [[_ALPHA]] transparency.
* When [[LONG]] values are [[PUT]] to file, the ARGB values become BGRA. Use [[LEFT$]]([[MKL$]]({{Parameter|color32value~&}}), 3) to place 3 colors.
* '''NOTE: Default 32-bit backgrounds are clear black or [[_RGBA]](0, 0, 0, 0). Use [[CLS]] to make the black opaque.'''
