CKEditor plugins not working/appearing - ckeditor

Question

I have followed the documentation and added two plugins:
enhanced image (image2)
enhanced color button
but neither appears in my toolbar. I have added all the dependencies.
Here's my config.js
CKEDITOR.editorConfig = function( config ) {
config.toolbarGroups = [
{ name: 'document', groups: [ 'mode', 'document', 'doctools' ] },
{ name: 'clipboard', groups: [ 'clipboard', 'undo' ] },
{ name: 'editing', groups: [ 'find', 'selection', 'spellchecker', 'editing' ] },
{ name: 'forms', groups: [ 'forms' ] },
'/',
{ name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ] },
{ name: 'paragraph', groups: [ 'list', 'indent', 'blocks', 'align', 'bidi', 'paragraph' ] },
{ name: 'links', groups: [ 'links' ] },
{ name: 'insert', groups: [ 'insert' ] },
'/',
{ name: 'styles', groups: [ 'styles' ] },
{ name: 'colors', groups: [ 'colors' ] },
{ name: 'tools', groups: [ 'tools' ] },
{ name: 'others', groups: [ 'others' ] },
{ name: 'about', groups: [ 'about' ] }
];
config.height = 500; // 500 pixels.
/*config.removePlugins = 'colorbutton';*/
config.extraPlugins = 'button', 'toolbar', 'notification', 'clipboard', 'lineutils', 'dialogui', 'dialog', 'widgetselection', 'widget', 'image2', 'panel', 'floatpanel', 'panelbutton', 'enhancedcolorbutton';
config.removeButtons = 'NewPage,Source,Scayt,Form,Checkbox,Radio,TextField,Textarea,Select,Button,ImageButton,HiddenField,Outdent,Indent,Blockquote,CreateDiv,BidiLtr,BidiRtl,Language,Anchor,Flash,SpecialChar,PageBreak,Iframe,BGColor,Maximize,ShowBlocks';
};
Any assistance is much appreciated.

Please see:https://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-extraPlugins
The list of plugins should be entered as a single string of comma separated values:
config.extraPlugins = 'button,toolbar,notification,clipboard,lineutils,dialogui,dialog,widgetselection,widget,image2,panel,floatpanel,panelbutton,enhancedcolorbutton';
NOTE: plugins like button,toolbar,dialog and dialogui, should be available in any preset so unless you are having some very customized package, there should be no need to add them with extraPlugins setting. They should already be in the package.
