Invoke I7 value-printing from I6?

I have an I7 “kind of value” which I wish to print from within the I6 PrintCommand routine. How can I invoke the I7 value-printer here?

It’s not directly accessible. It’s easiest to do this through an I7 phrase:

To print (C - color) (this is i6-color-printing): say C;

[then, in I6 code...]

	((+ i6-color-printing +) --> 1)(col);

Aha, nice. I didn’t know you could invoke a phrase like that. Thanks!
