Hello list, I'm not sure that following problem also occurs for Sebastian, but if I use PS-backend in the below script I get the attached output, where the upper part of the b is somehow hidden (matplotlib-version 0.98.6svn). Is this a problem of matplotlib or did I miss something in the tex-handling?
best regards Matthias

f = figure()
f.text(0.5, 0.5, r"{\color[rgb]{0,1,0} a } b {\color{blue} $\nu, \mu, \tau$}")
savefig('test_tex_color.ps')
