Nice!  How did you do the color coding?

But this gives you the Greek characters of the Symbol font.
Since Tinos also has Greek characters, it would be nice to
use the italic Tinos Greek for the math.  Could you maybe
try the trick of telling eqn

  chartype "letter" \[*a]\[*b]\[*g]\[*d]\[*e]\[*z]
  chartype "letter" \[*y]\[*h]\[*i]\[*k]\[*l]\[*m]
  chartype "letter" \[*n]\[*c]\[*o]\[*p]\[*r]\[*s]
  chartype "letter" \[*t]\[*u]\[*f]\[*x]\[*q]\[*w]

at the beginning (in the first EQ/EN pair)?



Attached is my own experiment of using a different Greek font
(GFS Didot) for the math.  Unfortunately I do not speak Greek,
so I have no idea whether the text is typeset correctly,
but I think the Greek typeface looks very nice.

I did the color coding by inserting color commands into
the intermediate output wherever a font change occurred.
The colors are:

  red:   Roman
  blue:  Italic
  green: Symbol

(The fraction bar is not from a font, but drawn as a line
while the blue color was active.)
