Shell and Eshell in emacs inherit from ansi-colors which affects how output from command line programs that make use of them. While many of the themes included with emacs define faces for them, others do not. Specifically adwaita, deeper-blue, light-blue, manoj-dark, tsdh-dark, tsdh-light, wheatgrass and whiteboard themes. This makes output from terminal applications that make use of ansi-colors look awkward or hard to read when using those themes(i.e. in shell or eshell). Is it possible to enforce definitions for ansi-colors at least in the themes that are included with emacs. Because interaction with the shells is an essential part of using emacs for so many people.
