[XeTeX] problem rendering unicode Devanagari dependent vowel signs in a different color

[ShreeDevi Kumar]

I was recently asked

To make study materials for my students I want to change different colors

for svaramatra. I used this one - à€•à¥ + à€‡ = à€•{\color{blue}à€¿} but the letter
not combines together How it is possible in latex.

I haven't been able to figure out a way to do it in xelatex.

Here is an MWE,

-------

\documentclass[11pt]{article}

\usepackage{polyglossia}

\usepackage{color}

\newfontfamily\hindifont [Script=Devanagari]{Jaipur Unicode NFLC}

\begin{document}

\hindifont{

à€•à¥ + à€‡ = à€•{\color{blue}à€¿} = à€•à€¿

}

\end{document}

-------

hope to get some suggestions on how to get the letter be one color and
Devanagari dependent vowel sign in another color and render correctly.

Hi,

I am afraid that this is impossible. \color inserts aa expandable command
of a main processor which must not be used inside a word.
This means that in the TeX's eyes the matra is a part of another word and
must not be connected. You have to do it manually.

Try this in your file and see the difference for I and U:

\hindifont{

à€•à¥ + à€‡ = à€•{\color{blue}à€¿} = à€•à€¿ = \textcolor{blue}{à€¿}à€•

à€•à¥ + à€‰ = à€•{\color{blue}\kern-.15em ु} = à€•à¥ = \textcolor{blue}{ु}à€•

}

Thank you so much for your prompt reply and solution to the problem.

I am attaching the MWE and pdf output using \textcolor.

Appreciate your help.
