I have search the web. I have tried color-theme (perhaps I need to create my own, but really I have my emacs set up the way I want it except for this ONE thing, and I could not find a color theme that was acceptable to me).
I just want to change the color of the directories in dired-mode. I have several custom colors changed in my .emacs, like:
(set-face-foreground 'font-lock-comment-face "yellow" )
But I just don't know what face to change for the directories in dired mode.
Can anyone help?
Thanks!
If you move point to the place that's displaying the color you want to change and run M-x describe-face, it will tell you the face for the text at point and that face's properties.
For me, it's dired-directory, not font-lock-comment-face.
Well, I managed to list the faces by doing M-x list-faces-display, and then I found the faces that had the dark blue that I didn't want, and, although none of the face descriptions said anything remotely like "Directory Name in dired", I just changed all of the faces that had unreadable colors, and my problems were solved!
(set-face-foreground 'dired-directory "yellow" )
The easiest way is to run:
M-x customize-face dired-directory
You'll then be presented with a menu of attributes you can customize. Select Save for future sessions and your .emacs will automatically be updated to make the change permanent.
diredful (dired colorful) worked for me.

To match directories:
Pattern: d.*
Select regexp on whole line (so it matches the permissions containing the 'd')
Check apply to Dirctories
Style the colors.
if you are using an older version of emacs (i tested emacs 21) try "list-text-properties-at" instead of "describe-face". for me, it shows the directory face as "font-lock-function-name-face".

The question says it all. I would like to change the background color of all sections labeled with a particular tag (e.g. :WORK:) in my org-mode file. I found out how to change the colors of the TODO states, but I wasn't successful in changing the color of the whole line. Can that be done? Thanks a lot in advance for your help.
You can use font-lock-add-keywords:
(font-lock-add-keywords 'org-mode
'(("^.*:write:.*$" . font-lock-keyword-face)))
See C-h f font-lock-add-keywords RET for details.
There is no such code that's ready to copy or use, AFAICT. Though, I'm sure it can be done, but will require hand-made code.
However, if you'd be interested to have such highlighting in the agenda buffer, you should check out some post of John Wiegley, a couple of years ago.
The slrn newsreader has an attractive interface with different colours for the author, subject and date columns when browsing list of articles in a newsgroup. I am looking for the Emacs font/face variables for these fields in gnus, but have not been able to find them. The gnus manual for faces does not list the available faces and none of the faces list in Emacs (M-x customize-face gnus-... looks relevant. I am using gnus 5.13 in Emacs 23.2.1.
(This question is not related to displaying "faces" (icons/avatars) in Emacs or gnus.)
Solved: See my answer below.
I think they're scattered a bit in the gnus codebase. The faces used in the article buffer are probably in gnus-art.el, etc.
It sounds like your biggest problem is that there are specific faces that you can't find the symbol for. You can always do M-x describe-face to see what is under the cursor to solve that problem.
Also, (face-list) returns a list of all defined faces. You could scan that list looking for things that look like likely candidates for the particular faces you're interested in.
The format string for various elements in gnus can be customized by modifying the appropriate variable. The variable for the summary line is gnus-summary-format-line. I am not using the default value for this variable, but instead am using the value %U%R%z %(%&user-date; %-15,15f %* %B%s%)\n.
As described here, a new face can be applied to any (sub)section of a format line by bracketing the section with %1{ and %}, where the 1 in this example corresponds to gnus-face-1. gnus-face-1 in my installation defaults to "italics", so adding the following to my ~/.emacs file results in the author in the summary line appearing in italics:
(setq gnus-summary-line-format "%U%R%z %(%&user-date; %1{%-15,15f%} %* %B%s%)\n")
I go with M-x list-faces-display (which opens a new buffer with all the currently defined face variables fontified to the color that they're set to, in alphabetic order) when I want to see what faces I need to change to get a mode working.
Then I setq them, using either the format from color-theme or from the new emacs built-in theme format, depending on which version of emacs I'm in.
Is it possible to select a piece of text you're editing and change its color? I know it's possible to create a color theme that will color certain kinds of text (like for example coloring functions in a certain programming language), but is it possible to do a one time color change to a selected piece of text in a specific emacs document without creating a theme? thanks in advance.
A theme doesn't allow you to specify the color of arbitrary text in any case. It only describes a set of face to be used by font-lock.
To apply a face to an arbitrary piece of text, select the text, then M-: (add-text-properties (region-beginning) (region-end) '(face font-lock-warning-face))
See the faces section of the elisp manual on how to create a face.
Emacs also comes with the hi-lock package, which can highlight regexps or lines containing regexps. See manual
how about M-x highlight-phrase ?
I know six years is a pretty long time, but I stumbled across this question and, after a lot of research, I did not find anything nearly as objective as what I eventually dug out for myself.
To color say, the first 200 characters in your buffer, execute the command:
(put-text-property 1 200 'face (cons 'foreground-color "red"))
If you need help executing this command in emacs, here is one possibility among many:
Type ESC-x eval-expression.
Type or paste the above command in the mini-buffer after the prompt.
Press ENTER.
You might like to look at enriched-mode.
If you are in a buffer that isn't controlled by font-lock, you can use 'facemenu'.
For example, highlight a bit of text, then with the mouse, press C-mouse-2. You can then select a face (some combination of text properties with a name). You can also pick random forground or background colors.
If you Emacs is particularly old, I seem to remember something similar on M-g.
Try set-background-color, set-foreground-color, set-cursor-color.
Changes won't be saved with the document though.
Note:
When I try those functions, they don't set the region's color unless I go through the menus.
See http://www.emacswiki.org/emacs/HighlightTemporarily (and it need not be temporary).
You can "color" text by swiping it with the mouse, or matching it with a regexp, and several other ways. Library highlight.el, in particular, lets you "color" text in many ways.
I highlight current line by evaluating:
(hl-line-mode)
It could also be set globally:
(global-hl-line-mode nil)
The problem is that this way line highlighting overrides highlight-phrase. So my question is: "how to highlight both current line and a given phrase in this line?"
Both highlight-phrase and hl-line apply faces that have a background color set. hl-line wins because it uses an overlay, and overlays always override text properties, which highlight-phrase uses. I suggest that you work around this by customizing the hi-yellow face to use a bright foreground color instead of a background color, or even a box.
So here's some, definetly not ideal, solution. Do:
M-x customize-face
emacs then asks you which one, and I did
hl-line
Then I turned off "inherit" flag (the last one), and turned on the "foreground" flag, - it was saying "black" - I made it red. After that You should save it all at the top of the page - either - for this seccion only, or for future sessions too.
That's it! This way current line text arrears of red font, while highlight-phrase highlights the phrase with yellow.
Edit: The previous solution that I posted doesn't work, but this one should.
Highlight has two modes, one for font-lock-enabled buffers (which uses font-lock) and one for without (which uses overlay). The solution I found was to simply force highlight to use overlay at all times, and thus have higher priority over hl-line (because shorter overlays have an implicitly higher priority, given the same value of priority).
To do this I went into hi-lock.el and replaced every instance of font-lock-fontified with nil. Be sure to M-x byte-compile-file afterwards in order to update hi-lock.elc.
I am using a clone of the wombat Vim color scheme in eclipse for Python development and it works well apart from the matching keyword highlight (whatever that is named), which is ffff96. This pale yellow makes it impossible to read the white foreground text. Anyone know where this is set?
Oh! Found it! General->Editors->Text Editors->Annotations->Occurences(Pydev). Awesome. What a mess.
Agree with Paul this is a mess; you have to know the name of what you're looking for in order to find it. Bleh. However, here are actual locations for the underlying settings strings (with thanks to Frederic):
In the file {Eclipse workspace directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.editors.prefs :
Here are the python-specific and general text colors for matching keywords (they call it "Indication"):
pydevOccurrenceIndicationColor=106,105,146
occurrenceIndicationColor=97,97,97
Also, if you're looking for a specific value that you can find in the UI but not in a file you can change it in Eclipse to a known RGB value and grep for that in the .settings dir.
