Error Message from Color module with CKEditor

I'm seeing that exact same errors.

To get rid of these warnings, I re-enabled the site's theme (somehow it was set as the default but not enabled) and reselected the administration theme. A similar problem is noted at http://drupal.org/node/290009.

Update: I spoke too soon. These warnings are still being displayed.

Same problem here.

Me too, using a Marinelli-based theme.

I need more infrmation, i cannot confirm this bug.
Could you provide me a list of installed modules with their version numbers?
Could you give a name and version of theme which were used ehwn these warnings occur?
You can also give me helping hand with write about Drupal version.

Ok, it seems we can reproduce this bug.
1. Start with Garland theme
2. In CKEditor profile change "User Interface color" to "Color module: base"
3. Save CKEditor profile
4. Change theme to Bluemarine (doesn't support color module)
5. Go to node/add/page
6. Result:

Warning: array_keys() [function.array-keys]: The first argument should be an array in D:\xampp\htdocs\drupalck\modules\color\color.module on line 138
Warning: array_shift() [function.array-shift]: The argument should be an array in D:\xampp\htdocs\drupalck\modules\color\color.module on line 139

It looks like color module developers overlooked something in color.module. Reported on Drupal project issue page (#654266: color_get_palette warnings).
Patch harden ckeditor.module for this bug.

Use the dev release until the next stable version of CKEditor module is available.

Hello,
Thanks for this dev release : it works fine !
And congratulations for this new wonderfull module : strong, fast and very nice !!! Its father FCKEditor can rest in peace.
Happy new year!
