{A case study on \TeX's superior power: Giving different colors to building blocks of Korean syllables} {Jin-Hwan Cho} {In 2007 Dave Walden, the instigator and primary interviewer of TUG's Interview Corner, tossed a tricky question at me. ``One of the concerns of many people in the \TeX\ world is that \TeX\ is relatively unknown in the larger worlds of typesetting and word processing compared with commercial programs such as Adobe's InDesign and Microsoft Word. How do you see the future of \TeX\ when it comes to Asian languages?'' Since then, it has been my mission to find a wonderful answer, that is, a \TeX\ product which other programs cannot reproduce. Unicode contains 11,172 modern Korean syllables all of which are composed by only 24 building blocks. In this talk, I will show an interesting \TeX\ example containing a large number of Korean syllables each of which is grouped by building blocks of different colors. Nobody, of course, will try to reproduce the example with other commercial programs.}
