The '''PALETTE''' statement can swap color settings, set colors to default or set the Red, Green, Blue color palette.



''RGB'' {{PageSyntax}} 

:::PALETTE [''attribute'', ''Red'' + (''Green'' * 256) + (''Blue'' * 65536)]

''Swap'' {{PageSyntax}} 

:::PALETTE [''set_attribute'', new_attribute]


* ''Red'', ''Green'' and ''Blue'' values can be from 0 to 63. Many color shades possible in non-[[DAC]] color attributes.
* If the Red, Green and Blue color intensity settings are all the same value the color is greyscale.
* Screens 0, 7 and 9 ([[DAC]]) colors cannot be changed by the RGB syntax statement in QBasic! Can use [[OUT]] to change attribute 1 thru 5 intensity settings.
* A swap is often used with [[DAC]] color attributes that cannot change RGB settings. Only the RGB color settings are swapped from original ''set_attribute'' to ''new_attribute''. Screens 0 thru 9 support swaps. Screen 10 up to 8 only.
* PALETTE without any value sets any changed RGB settings back to the Qbasic default color settings including [[DAC]] colors.
* [[PALETTE USING]] can be used when color intensity values are stored in an [[Arrays|array]].


''Example:'' Displaying all 64 DAC color hues as backgrounds in SCREEN 9 using a PALETTE swap.

{{CodeStart}} '' ''
  {{Cl|SCREEN (statement)|SCREEN}} 9 ' background is default black
  {{Cl|LOCATE}} 20, 33: {{Cl|PRINT}} "Press any Key!"  
  {{Cl|FOR...NEXT|FOR}} i = 1 {{Cl|TO}} 64
   a$ = {{Cl|INPUT$}}(1) ' wait for a keypress
   {{Cl|PALETTE}} 0, i
  {{Cl|NEXT}} '' ''
{{CodeEnd}}
:''Note:'' Other attributes(1 to 15) can be swapped for DAC foreground colors also.
