Setting Automatic Categories Possible? Help Requested.

[Fsuga]

Perhaps I have just lost my mind, because I think this should have a fairly
obvious solution:

Is there a way to have emails sent from contacts already in your contacts
(with the corresponding email address) to be automatically marked with the
colored category square that they are assigned on their contact page?

Example, if my sister is marked in my contact list as 'yellow,' when mail
from her address shows up, I would like the yellow box to already be there,
as opposed to assigning it myself.

Any help would be appreciated. I am brand new to Outlook, and don't know if
what I'm asking for is even possible.
Thanks.

No, you cannot match it like that, but you can do it with a sending rule
though;
Tools-> Rules and Alerts...
