In that case, one can also change the background colour, and in-border colour (used for the graphics), and auxiliary colour each line. And, by cycle-exact splitting, provide an independent out-border colour for each raster as well. My
MG raster engine is able to do that.
But a 'pure' MG screen doesn't need nor employ any raster effect.
I don't know how MINIGRAFIK works, if you have white background and black border on all of those images?
PGM IMPORT sets the border to black, and all foreground attribute cells to white, multi-colour enabled. Background, and auxiliary colour are the two intermediate colours, and they can both be chosen from all 16 available colours.
Of course this does not fully exhaust the capabilities of MINIGRAFIK. Each of the 20x12 attribute cells (with 8x16 hires pixels size) can have a different foreground colour, and multi-colour enable bit - besides the three global colours. Those degrees of freedom are fully accessible with MINIPAINT, and can already provide quite colourful results, without an apparent colour scheme as with PGM IMPORT. Mermaid has shown me some excellent examples.
Even though background colour, and auxiliary colour offer free choice of colours, one of them also - normally - is displayed in hires parts of the screen. Which would eventually lead to inverted letters in background colour (but not white) over black foreground. If one of the two intermediate colours is of the lower eight ones, that one might be used as foreground instead, setting background to white (still with inverted letters in the text part). This needs only small changes in PGM IMPORT.
Otherwise it is still feasible to do two raster splits between the graphics, and text part, to change background to black, so foreground could be white again, with non-inverted letters (and change background back again to the graphics part value outside the visible area).

P.S.: And Orange/Light Orange is the default setting in PGM IMPORT.
