No, sidebar icons should be there, as uncolorful as they may be.
Sounds like Sidebar prefs are wonky...
Go to your Finder "Go" menu hold the option key and choose Library. Then go to Preferences folder and trash these files:
Then, restart, or log out and in again.
(You will have to reset a few finder prefs the way you like them.)
I had this same issue and what worked for me was to delete the SIMBL folder (it's basically a plugin) from the main library's application support folder. This brought all the icons back---at least.
I really don't get why the color icons went black and white without providing you the option to turn on the color. It doesn't make sense for Apple to drain the color from eveything---VERY DISAPPOINTING.
Hopefully Panic's "Candy Bar" will be updated for ML and we can finally choose our own icons again.
I'm lurking and watching for people's experiences with ML before I upgrade, and this was one very persuasive reason NOT to upgrade yet.
I'm still reeling from the upgrade to Lion and its idiotic use of Kernel task.
I did find a nice little fix called sideeffects on MacUpdate that at least brings the color back to Finder. Now if I can only find something for iTunes and Aperture I'll be all set (until the next color drain.)
I had this problem too. I had installed Colorful Sidebar and after my Mountain Lion installation, I had no icons at all. (Although when I looked at the individual folders, they still had the custom colored icons.)
To summarize, if you lost your icons from Colorful Sidebar:
- Delete the SIMBL folder. You can go to Finder > Go > Go to folder... and type /Library/Application Support (pro tip: when you type to navigate to a folder like this, or in Terminal, you can type the first couple of letters and press TAB to autocomplete the folder or file name). You should see the SIMBL folder there and can delete it.
- Find the plist files and delete them: Finder > Go > Go to folder... and type ~/Library/Preferences. Delete com.apple.finder.plist and com.apple.sidebarlists.plist
- Restart Finder. (This worked for me; you may have to restart your computer. I also lost my custom sidebar preferences, i.e. the list of shortcuts I had there, so if it's tedious for you to recreate the list you may have to weigh the pros and cons.)
...And agree, I hate the lack of color too. It gives another dimension of visual variance to help select items from the list. (Plus, I have two "Documents" folders there — one my personal docs folder, the other is the Apache webserver Documents folder, and as there's no way to change the sidebar name without changing the underlying folder name, the only way I can tell them apart easily is with the icons.)
I had the same problem, but I found the following solution and now have my nice little color icons back in Finder:
Click on the "more..." link for complete instructions.
i didn't exactly loose my icons, they only lost their color & went back to their ugly grey selves as when i upgraded to Lion...
without wanting to hijack this thread this here worked like a charm for me - half a dozen clicks & BAM !!! color icons are back
have a look maybe it might help ? here :
i just CAN'T understand what the problem is to allow people to have colored or customized icons, have filed many feedbacks to Apple but no one ever bothered answering - it could even be there is a logical, sensible reason but not explaining it REALLY DOESN'T help
it's been a long time... ;-)
i don't know EXACTLY why/how/what - i'm NOT versed enough in these matters BUT yesterday i had tried it & it also DIDN'T work for me !?
then before going to bed i uninstalled every last trace of Simbl & Colorfulsidebar, today i downloaded Sideeffects again, tried installing & here it is
