{{DISPLAYTITLE:_PALETTECOLOR}}
The _PALETTECOLOR statement sets the color value of a palette entry of an image using 256 color modes or less (4 or 8 BPP).


{{PageSyntax}}
:[[_PALETTECOLOR]] {{Parameter|attribute%}}, {{Parameter|colour&amp;}}[, {{Parameter|Dest_Handle&amp;}}]


{{PageDescription}}
* The {{Parameter|attribute%}} is the palette index number of the color to set, ranging from 0 to 15 (4 bit) or 0 to 255 (8 bit) color modes.
* The [[LONG]] {{Parameter|colour&amp;}} is the new color value to set using [[_RGB32]] or [[_RGBA32]] values or using [[HEX$ 32 Bit Values]].
* If {{Parameter|imageHandle&amp;}} is omitted, [[_DEST|destination]] is assumed to be the current write page or screen surface.
* If {{Parameter|index%}} is outside of image or [[SCREEN|screen]] mode attribute range(0 to 15 or 0 to 255), an [[ERROR Codes|illegal function call]] error will occur.
* If {{Parameter|DestHandle&amp;}} does not use a palette, an [[ERROR Codes|illegal function call]] error occurs. '''Will not work in 24/32 bit color palette modes!'''
* If {{Parameter|imageHandle&amp;}} is an invalid handle value, an [[ERROR Codes|invalid handle]] error occurs.

::: ''Note:'' '''QB64''' 32 bit color intensity values from 0 to 255 can be found by multiplying above values by 4.

''Summary:'' The red, green, and blue intensity values can be changed using [[OUT]] or [[PALETTE]] statements. Some '''Qbasic''' RGB color attribute values can be changed in [[DAC]] {{KW|SCREEN (statement)|SCREEN}} modes and the [[DAC]] RGB intensity settings may be different. 


''Example:'' Creating custom background colors in SCREEN 0 that follow the text. [[CLS]] makes entire background one color.
