CALL PALETTE in Hangul Basic and Kanji Basic
Effect
Alters MSX colors palette, just like the standard COLOR= command.
If you have activated one of the Japanese text screen modes with CALL KANJI, you need to use this command instead of COLOR= that is disabled in these modes.
Version 4 of Hangul BASIC developed by Korean MSX fan Plaire extends this command to non-Korean MSX2, MSX2+ and MSX turbo R machines.
Syntax
CALL PALETTE (<Color>,<RedLuminance>,<GreenLuminance>,<BlueLuminance>)
Note: No parameter can be omitted.
Parameters
<Color> is a number between 0 and 15. It can be a numerical constant variable, an array variable or an expression.
Note that color 0 is a transparent color, it means that border space is seen transparently - to handle it as a 'normal' color, you need to use VDP(9)=VDP(9) OR &H20 (back to transparent feature with VDP(9)=VDP(9) AND &HDF).
<RedLuminance>, <GreenLuminance> and <BlueLuminance> are numbers between 0 and 7.
If you omit all parameters (execute simply CALL PALETTE), all palettes return to default.
Example
_PALETTE (7,4,3,5)
Default palette for Kanji text screens

| 3 | 3 | 7 | 3 | 7 | 2 | 6 | 7 | 11 | 6 | 6 | 4 | 15 | 7 | 7 | 7 |
Storage of palette in VRAM for Kanji text screens
MSX-BASIC stores/restores palette to/from VRAM, but the address is different for each graphic mode used by the Kanji text screen. The palette is stored in VDP native format.
| Used graphic SCREEN | Decimal | Hexadecimal |
|---|---|---|
| 5 | 30336 | 7680 |
| 7 | 64128 | FA80 |

CALL PALETTE in RMSX Basic
Effect
Selects the palette or monitor emulation to be used on the MSX1 computer emulated on a turbo R machine by the rMSX emulator.
Note: This instruction has no effect on MSX2 emulation, but it will not cause an error, even if used in a BASIC listing.
Syntax
CALL PALETTE <Palette/MonitorEmulation>
Parameters
<Palette/MonitorEmulation> can be MSX1, MSX2, GREEN or GRAY.
When this parameter is not specified, the MSX1 palette will be used.'
