Or, as requested, make it completely red:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\begin{document}
\tdplotsetmaincoords{70}{135}
\begin{tikzpicture}[scale=3,opacity=0.0,tdplot_main_coords,fill opacity=0.7]
\tdplotsphericalsurfaceplot{72}{36}%
{sqrt(15/2)*sin(\tdplottheta)*cos(\tdplottheta)}{transparent!0}{red}%
    {\draw[color=black,thick,->] (0,0,0) -- (2,0,0) node[anchor=north east]{$x$};}%
    {\draw[color=black,thick,->] (0,0,0) -- (0,2,0) node[anchor=north west]{$y$};}%
    {\draw[color=black,thick,->] (0,0,0) -- (0,0,2) node[anchor=south]{$z$};}%
\end{tikzpicture}
\end{document}

But IMHO this does not make much sense.

Maybe something like

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\begin{document}
\tdplotsetmaincoords{70}{135}
\begin{tikzpicture}[scale=3,opacity=0.0,tdplot_main_coords,fill opacity=0.7]
\tdplotsphericalsurfaceplot[parametricfill]{72}{36}%
{sqrt(15/2)*sin(\tdplottheta)*cos(\tdplottheta)}{transparent!0}{\tdplottheta}%
    {\draw[color=black,thick,->] (0,0,0) -- (2,0,0) node[anchor=north east]{$x$};}%
    {\draw[color=black,thick,->] (0,0,0) -- (0,2,0) node[anchor=north west]{$y$};}%
    {\draw[color=black,thick,->] (0,0,0) -- (0,0,2) node[anchor=south]{$z$};}%
\end{tikzpicture}
\end{document}

would make more sense.

See the description of \tdplotsphericalsurfaceplot in the tikz-3dplot manual for more information.
