If you can find the appropriate black symbol, then it can be colored easily: \documentclass{article} \usepackage{amssymb} \usepackage{xcolor} \begin{document} $\triangledown \blacktriangledown \begingroup \color{blue} \blacktriangledown \endgroup$ \end{document} If the symbol is a math symbol, then the color should be set via: ...

A possible way: \documentclass[12pt]{article} \usepackage{amsmath,amssymb} \usepackage[dvipsnames]{xcolor} \usepackage[geometry]{ifsym} \begin{document} Example: {\color{SeaGreen}\FilledBigTriangleDown} \end{document}

This answer amplifies on the accepted answer. As many have noted in other answers, using MnSymbol package changes many glyphs, which is usually not wanted. So the approach mentioned in a number of answers is to import just the desired glyphs from MnSymbol. leaving all the others intact. The "value added" I perform here, since that approach seems to be ...

May be the “unicode way”: \documentclass{scrartcl} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \DeclareUnicodeCharacter{00B7}{\ifmmode\cdot\else\textperiodcentered\fi} \begin{document} I'm new to \LaTeX, and I have no idea how to type this ·; in \LaTeX. \end{document} If you don't want to use the unicode point in \DeclareUnicodeCharacter you ...

I was always taught that the dollar sign was originally created as a superposition of "U" and "S", a uniquely American symbol. Thus, for a really old version of the symbol, I build it here from scratch. Here, I show the serif and sans versions of the "S". \documentclass{article} \usepackage{stackengine,graphicx} \def\origdollar{% ...

You can often find the fonts you want by searching on detexify Try \documentclass{article} \usepackage{textcomp} \begin{document} \textdollaroldstyle \end{document} That may seem like a lot to write out, so in your preamble you can put \let\dollar\textdollaroldstyle and then you can write \dollar3.50 in you document and get the proper symbol.

If you want a Fraktur or Semi-Fraktur dollar sign, see the Rotunda capital S: However, I have not been able to find a matching font file. Take a look at the dollar sign in http://www.abstractfonts.com/font/14113/charmap?frameless=1&rndint=4637722&brief=1. This is only one typeface in http://www.abstractfonts.com/category/31/Calligraphy. Several ...

Not \=i\ but \=\i \i is the dotless i command. If you use \usepackage[utf8]{inputenc} then you should just be able to type Ibn-Sīnā directly. \documentclass{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \DeclareUnicodeCharacter{012B}{\=\i} \DeclareUnicodeCharacter{0101}{\=a} \begin{document} [ Ibn-Sīnā ] or [ Ibn-S\={\i}n\={a} ] ...

I had this exact problem recently! I tried two things: I added \usepackage[utf8]{inputenc}, with no success. I tried another, related package approach, but had no luck with that, either. I manually replaced the offending apostrapes with ones I typed freshly. This worked. To make this more efficient, you might consider doing a find-and-replace. This worked! ...
