set the highlight color when searching

set the highlight color when searching

[gerlach]

Hi,
when searching for text the actual highlighted text in emacs 23.3 in 
ubuntu 12.04 is lightblue with pink background - a horrible combination, 
I often can't read it. How can I change lightblue to e.g. white?

thx
Eckard

Customize the face 'isearch'.

How to find this yourself:

M-x customize-apropos-faces RET isearch RET

You will see these matches:

Isearch face: (sample) [Show Face]
   State: HIDDEN, invoke "Show" in the previous line to show.
   Face for highlighting Isearch matches.

Isearch Fail face: (sample) [Show Face]
   State: HIDDEN, invoke "Show" in the previous line to show.
   Face for highlighting failed part in Isearch echo-area message.

Isearch Lazy Highlight Face:(sample) [Show Face]
   State: HIDDEN, invoke "Show" in the previous line to show.
   isearch-lazy-highlight-face is an alias for the face `lazy-highlight'. [More]

You can customize any of these from the same buffer (it is a Customize buffer).
Start by clicking `[Show Face]' (or the small triangle in Emacs 24+).

If you generally use the default Emacs settings, and you think the default
appearance for face `isearch' should be changed, file an enhancement request for
that using `M-x report-emacs-bug'.

some hours later I made some further tests:
green works, black, too! And red also, but not white and yellow! Who has 
programmed such nonsense? All useful colors are blocked!?!?!

In another test I saved "black" as background and got "black" in .emacs 
but red in emacs search !?!?! I tested all colors changing

  (custom-set-faces
  '(isearch ((((class color) (min-colors 8)) (:background "white" 
:foreground "black"))))

background entry. Only "green" appears as green, all other colors change 
to other colors! What a mess! Inserting "white" results in blue (cyan) 
background, and in combination with foreground black (that appears as 
black, what a surprise!)  I CAN WORK!!! Black on cyan is readable!!! GREAT!

As next "isearch-fail" was also unreadable , red background and grey 
foreground. I went to configuration with
M-x customize-apropos-faces RET isearch RET
and saved somewhat color for background.  I looked at my .emacs file and 
detected:

'(isearch-fail ((((class color) (min-colors 8)) (:background "red")))))

I tested all possible colors yellow, black, green, .... All colors 
appeard in other color like observed with "isearch", inserting "cyan1" 
instead von red  I get  lightblue (=cyan) at isearch-fail. And I CAN 
READ IT AND I CAN WORK! What surprise and what a mess ...

After I detected that "isearch" was resetted to magenta background ..., 
I looked at .emacs and indeed: emacs config has manipulated the colors 
in isearch entry although I didn' change "isearch" in  M-x 
customize-apropos-faces RET isearch RET !! What mess, bugs-over-bugs ... 
  in
emacs 23.3+1-1ubuntu9.1

`M-x list-colors-display' will show you some colors you can use.  
When I do that, `white' is one of the possibilities.
If it is a possibility for you too, then try again.

The `custom-set-faces' entry added by Customize to your .emacs says that your
Emacs must support at least 8 colors for that entry to have an effect:
`(min-colors 8)'.

What happens if you edit the face in Customize as you want, then set that
change, and then in the same Emacs session you use isearch?

(Works for me.)

I think you should use a terminal with some more than eight colours…

Could you try M-x list-colors-display RET ?

Seems that he only treats Emacs/Vim as a toy, not a tool for
editing or even programming.

Anyway, he succeeded to unsubscribe the list.

I use emacs extensively for coding. It's actually all I use.

Are you confused by the setting of isearch-lazy-highlight-face? Isearch high-light three sorts of places: the found string, matching strings between here and the beginning of the buffer, and matches between here and the end of the buffer. You should customise all three variables to see the real change.

You're right! i didn't know that the limiting software is my XFCE 
0.4.8-Terminal (XFCE 4 Desktop).

$ tput colors
8


M-x list-colors-display RET
results in 8 colors: white is displayed as lightblue, yellow as purple, 
, then black, green, blue, magenta, cyan. So I've no "light"  colors. I 
could update to XFCE 0.6 terminal but at the moment it's not worth it, 
I've found a color combination with that I can work with.

thx to all for you help!

You can configure XFCE Terminal to use any 16 colors (8 basic colors
and 8 for bold text).

You can also configure XFCE Terminal to support 256 colors.

I am describing the current version that ships in XFCE 4.10 but I am
pretty sure basic color configuration was there in 4.8, too.
