Grab user information in templates

[TruthElixirX]

I need to grab userinfo from a specific field to be used in the templates. Would the correct syntax be:

$userinfo[field6];

to get user information and insert it somewhere like

<div style="background-color:$userinfo[field6];">

and on the field name do I use the id or name?

Right now using the above code I get:

<div style="background-color:;">

It isn't grabbing the profile field.
