A word for neutral quality?

A bad quality might be a 'sin' or 'flaw', and a good quality a 'grace' or 'virtue'. Is there a term like this for a neutral quality? If there is no term is there an idiom or slang?

Solution 1:

Nethawk,

I would note that the word quality is, itself, neutral:

quality: an inherent feature : PROPERTY (Websters)

Other, similarly neutral, words that come to mind include:

attribute: a quality, character, or characteristic ascribed to someone or something. (Websters)

characteristic: a distinguishing trait, quality, or property (Websters)

trait: an inherited characteristic (Websters)

and

feature: a prominent part or characteristic (Websters)
