RGB Function
RGB(red, green, blue)

Combines three integers into a single RGB colour value. Each parameter must be an integer in the range 0–255:

  • red → intensity of the red channel
  • green → intensity of the green channel
  • blue → intensity of the blue channel

Examples

REM Create pure red
col = RGB(255, 0, 0)
PRINT "Red = "; col
REM Create a shade of purple
col = RGB(128, 0, 128)
PRINT "Purple = "; col
REM Use in drawing
GCOL RGB(0, 255, 0)
RECTANGLE 10, 10, 100, 50

Notes

  • The return value is a 24-bit RGB colour packed into an integer.
  • Valid range for each channel is 0–255; values outside this range are clipped.
  • Typically used with graphics commands such as GCOL and RECTANGLE.
