I'm not as convertible as Skip Cave. I don't think that overlapping with the APL character set is a very good idea.
How about this for another approach: Provide an option whereby J. primitives can be displayed as the base J character but in (say) red, and J: primitives can be displayed in (say) green. Simple, eh? Compatible, too. And colour-blind people can simply opt to go with the original. Later on, negative numbers can be shown optionally in red (accounting fashion).
