Suggestions needed for new Pygments syntax highlighting lexer for Saturn assembly

[Jonathan Busby]

I've been re-working the HP Saturn Wikipedia article and I would like to have the example assembly code section syntax highlighted. This is done with the Python based Pygments library. I have to implement a new lexer for HP Tools / Jazz syntax. This in itself isn't that difficult ( see : https://pygments.org/docs/lexerdevelopment/ ) but I'd like to know if anyone has any suggestions for how the elements of the assembly source should be colored. I took a look at the Debug4x syntax highlighter and I don't particularly like its choice of colors, so suggestions are welcome. I need color suggestions for :

• macros
• instructions
• register fields
• registers
• comments
• conditional compilation pseudo-ops
• labels
• and possibly some other things that I've forgotten to list
  

Any suggestions would be very welcome.

Regards,

Jonathan
