Setting plot foreground colour in 32-bit (24-bit) modes?

I feel really thick asking this question, but I can’t find a way to say “plot in colour #FA8072” anywhere. (That’s Salmon, rgb(250, 128, 114), btw.)

Whatever it is has to update FgEcfOraEor internally, if that helps?

We can’t still be limited to GCOL colours, can we?

Yup, it’s a BBC Micro really. Use SWI ColourTrans_SetGCOL

So, pass &FA807200 in R0?

Entry
R0 Palette entry
R3 Flags
R4 GCOL action (only the bottom 3 bits are valid)

The palette entry is &BBGGRR00 format

&7280fa00 works, thanks.

GCOL 250,128,114 works fine here (or GCOL &FA,&80,&72 if you prefer).
Where’s the problem?

GCOL 250,128,114 works fine here

For which BASIC calls SWI ColourTrans_SetGCOL to do the biz.

So what?

So what?

Simon is doing low-level stuff to replace the kernel, so needs to know the mechanisms involved.
