Hello all, I was wondering how to make that nice looking Complex 'C' when writing a set in Latex. For example,
$$\{k\in C\mid k>0\}$$ looks okay but can be better.

\mathbb{C}? (The ? is not a part of it)

$$\{k\in \mathbb{C}\mid k>0\}$$

That's it, thanks!

No problem! For future reference, other common LaTeX fonts include

Bold \mathbf $\mathbf{a},\mathbf{A}$
Roman (not italicized unlike the regular math text) \mathrm $\mathrm{a},\mathrm{A}$
Fraktur \mathfrak $\mathfrak{a},\mathfrak{A}$
Calligraphic \mathcal $\mathcal{A}$
Script \mathscr $\mathscr{A}$

And probably something I forgot.
