* The value returned is either the closest color attribute number or a 32-bit [[_UNSIGNED]] [[LONG]] color value.
* '''Return variable types must be [[LONG]] or the 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.
* The [[_ALPHA|''alpha&'']] value can be set to make the color transparent (0), opaque (255) or somewhere in between.
* Parameter values outside of the 0 to 255 range 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|colorIndex~&}}), 3) to place 3 colors.
* If {{Parameter|imageHandle&}} is omitted, the image is assumed to be the current [[_DEST|destination]] or [[SCREEN]] page.
* Allows the blending of pixel colors red, green and blue to create any of 16 million colors.
* '''NOTE: Default 32-bit backgrounds are clear black or [[_RGBA]](0, 0, 0, 0). Use [[CLS]] to make the black opaque.'''
