As you can see the foreground of suffix compress file is correct (orange). Nice.

But the foreground of name compress file is not change (must be blue).

Put your cursor on a colored character and use C-x =. Near the bottom of buffer *Help* you'll see the faces used for that character.

Use M-x customize-face to customize any face. Save your changes (in Customize).

On the suffix for a compressed file, C-x = tells me this:

There are text properties here:
  dired-filename       t
  face                 diredp-compressed-file-suffix
  fontified            t
  help-echo            diredp-mouseover-help
  mouse-face           highlight

On the base file name (not the suffix), C-x = tells me this:

There are text properties here:
  dired-filename       t
  face                 diredp-compressed-file-name
  fontified            t
  help-echo            diredp-mouseover-help
  mouse-face           highlight

M-x customize-face RET diredp-compressed-file-name RET will tell you how that face is currently defined, and let you change its appearance.

However, option diredp-ignore-compressed-flag controls this also, and by default it is non-nil:

diredp-ignore-compressed-flag is a variable defined in dired+.el.

Its value is t


Non-nil means to font-lock names of compressed files as ignored files.

This applies to filenames whose extensions are in diredp-compressed-extensions. If nil they are highlighted using face diredp-compressed-file-name.

Note: If you change the value of this option then you need to restart Emacs to see the effect of the new value on font-locking.

You can customize this variable.

So if diredp-ignore-compressed-flag is non-nil then the face you might want to customize is diredp-ignored-file-name. (And in that case, *Help* will have told you that that's the face used on the base file name.)

The Dired+ doc (see the Commentary in file dired+.el, for instance) tells you:

You can use key C-down or C-up to navigate to the next or previous file line, respectively, and at the same time show its file in another window. The focus remains on the Dired buffer. A numeric prefix arg means move that many lines first.

Names of files and directories that match either of the options diredp-visit-ignore-extensions or diredp-visit-ignore-regexps are skipped.

This is one reason that compressed files are "ignored", by default: when cycling among files in a listing using, say, C-down, you generally might not want to open compressed files. If this is the case then you will want to add their extensions (e.g. Z, tgz, etc.) to the value of option diredp-visit-ignore-extensions.

UPDATE after your comment:

You added a comment that says that your diredp-ignore-compressed-flag is nil, but (I guess?) you're still seeing its non-nil effect.

Your saying only this tells us nothing helpful:

"C-x =" - Char: m (109, #o155, #x6d) point=947 of 1210 (78%) column=49

You need to look at the bottom of the *Help* buffer, to see what face is being used there. See what I wrote and show, above.

I'm guessing you didn't save the nil value after changing option diredp-ignore-compressed-flag to nil with M-x customize-option. Or if you did, you didn't start a new Emacs session to see the effect.

Did you read this part of the dired+.el Commentary?

;;  A few of the user options defined here have an effect on
;;  font-locking, and this effect is established only when Dired+ is
;;  loaded, which defines the font-lock keywords for Dired.  These
;;  options include `diredp-compressed-extensions',
;;  `diredp-ignore-compressed-flag', `dired-omit-extensions', and
;;  `diredp-omit-files-font-lock-regexp'.  This means that if you
;;  change the value of such an option then you will see the change
;;  only in a new Emacs session.

In other words, you need to (1) change the option value to nil, (2) save that change, and (3) start a new Emacs session to see the effect of the change.

  • "Diredp Ignore Compressed Flag" is nil. But it not help. Compress file name not set to blue color. "C-x =" - Char: m (109, #o155, #x6d) point=947 of 1210 (78%) column=49 Commented Mar 30, 2023 at 21:51
