{{DISPLAYTITLE:_RGB}}
The [[_RGB]] function returns the closest palette attribute index (legacy SCREEN modes) OR the [[LONG]] 32-bit color value (32-bit screens). 


{{PageSyntax}}
: {{Parameter|colorIndex~&amp;}} = [[_RGB]]({{Parameter|red&amp;}}, {{Parameter|green&amp;}}, {{Parameter|blue&amp;}}[, {{Parameter|imageHandle&amp;}}])


{{PageDescription}}
* 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 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.
* Intensity values outside the valid range are clipped.
* Returns [[LONG]] 32-bit hexadecimal values from '''&amp;HFF{{text|00|red}}{{text|00|green}}{{text|00|blue}}''' to '''&amp;HFF{{text|FF|red}}{{text|FF|green}}{{text|FF|blue}}''', always with full [[_ALPHA]].
* When [[LONG]] values are [[PUT]] to file, the ARGB values become BGRA. Use [[LEFT$]]([[MKL$]]({{Parameter|colorIndex~&amp;}}), 3) to place 3 colors.
* If the {{Parameter|imageHandle&amp;}} is omitted the image is assumed to be the current [[_DEST|destination]] or [[SCREEN]] page.
* Colors returned are always opaque as the transparency value is always 255. Use [[_ALPHA]] or [[_CLEARCOLOR]] to change it.
* '''NOTE: Default 32-bit backgrounds are clear black or [[_RGBA]](0, 0, 0, 0). Use [[CLS]] to make the black opaque.'''
