I'd like to have the equation colorization process be somewhat semantic, i.e., I can still type equations or math the ordinary way, except they occur in an environment in which the colorization happens automatically, so:


_1\psi_1 \left[\begin{matrix} a \\ b \end{matrix} ; q,z \right] 
= \sum_{n=-\infty}^\infty \frac {(a;q)_n} {(b;q)_n} z^n
= \frac {(b/a,q,q/az,az;q)_\infty }

would result in things like this:

without having to insert \color{} everywhere Is there a package which already does this?

    Automating that seems difficult. What you should do is define macros (specifying the style, colour) for your variables and use those macros throughout your derivation. – jubobs Feb 19 '14 at 15:51
  • Isn't this a symptom of sensory aphasia? – John Kormylo Feb 20 '14 at 18:34
  • @JohnKormylo: you're looking for synaesthesia. q-hypergeometric function identities mostly look like wallpaper -- see /Gasper & M. Rahman Basic Hypergeometric Series/ for instance and it is really difficult to follow what's going on. Color makes it easier, and I'd prefer to have an automatic mechanism for producing colorization. – Owen Maresh Mar 5 '14 at 19:33

    I am not ready to publish my project, yet, but I enclose a teaser for now. :-) striz7.fame.utb.cz/docasne/tex-sx/mal-math.pdf – Malipivo Mar 24 '15 at 7:48
