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


{{PageSyntax}}
:color32value~&amp; = '''_RGBA32('''{{Parameter|red&amp;}}, {{Parameter|green&amp;}}, {{Parameter|blue&amp;}}, {{Parameter|alpha&amp;}}''')'''


{{PageDescription}}
* The value returned is ALWAYS a 32 bit [[_UNSIGNED]] [[LONG]] color value. 
* '''Return variable types MUST be [[LONG]] or resulting color may lose the [[_BLUE]] value!'''
* {{Parameter|red&amp;}} specifies the red component intensity from 0 to 255.
* {{Parameter|green&amp;}} specifies the green component intensity from 0 to 255.
* {{Parameter|blue&amp;}} specifies the blue component intensity from 0 to 255.
* {{Parameter|alpha&amp;}} 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 '''&amp;H00{{text|00|red}}{{text|00|green}}{{text|00|blue}}''' to '''&amp;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$]]([[MKL$]](colorvalue&amp;), 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!'''
