Is it possible to make a keyboard shortcut for a specific color for fonts?

Question

I'm a novice InDesign user and these forums have been a great resource, so thank you for your time.
I'm doing a very complicated "text art" project and I'd like to be able to change text colors right from the keyboard.
In Word, one is able to make a keyboard shortcut (to an unused key combination) that would allow you to change text to white, for example and another combination to change it to black, etc.
I'd love to be able to do that in InDesign without having to mouse over to the color swatch or over to a paragraph style with the text color set.
Again, thank you in advance!

For anyone else who has this problem - I actually found out an easy workaround.
There's another forum that addresses the NumPad issue for MacBooks (http://forums.adobe.com/thread/324960) and I did a modified version for character styles v. paragraph styles per the final comment by Kaj-Ettore.
==
(1) Open text edit and copy the below script (for me it was changing the text to white):
try{app.selection[0].applyCharacterStyle
(app.documents[0].characterStyles.item(1),true)}catch(e){}
Watch the number '(1)' in brackets on the last line: This is the Style number according to the Styles listed in the 'Character Styles' Panel of InDesign (following "[None]").
Per my setup, "White" is 1 and "Black" is 2.
SEE SCREENSHOT:
Decrement the style you'd like to be applied via this script from the styles listed in the InDesign-applet 'paragraph styles'.
*Note - This Workaround only works for specific Documents – since InDesign links Styles with document templates.
(2)  Save the Script to:
%InDesign_Install_Folder%\Scripts\Scripts Panel\Samples\JavaScript\Style(%nmb%).jsx
or name the file as you like. You'll have to assign a keyboard-shortcut to this and other files later, so it is wise to choose a common and memorable syntax for naming, e. g. numbers or style-names. (I used Style(White).jsx)
(3)  Repeat this step for every style you'd like to be applicable via a keyboard shortcut...
This is my "Black" script:
try{app.selection[0].applyCharacterStyle
(app.documents[0].characterStyles.item(2),true)}catch(e){}
Saved as: Style(Black).jsx
Assign a Shortcut to the Script
(1)  Open InDesign > Preferences > Keyboard Shortcuts > %YourSetOfShortcuts%
(2)  Select 'Scripts'
(3)  Choose the first script you've written, e. g. 'style(body).jsx'
(4)  Create Shortcuts for Standard- and Text-Environment
(5)  Repeat for any script you've written
(6)  Done.
This worked perfectly for me and I can now use ONE keyboard shortcut (albeit 3 simultaneous keys) to change from black text to white text.
