Answer

The answer is

Honey

I am the color of first.

The 'color of first' being gold (e.g. gold medal), which is the color of honey. (@Brent Hackers for this one)

I am always good – I'll never be a brat.

Honey is sweet, and sweet could be considered synonymous with 'good' and antonymous with 'being a brat'.
Honey doesn't spoil or 'go bad', i.e. it's always good.

I am made by number 2.

Honey is made by a bee; 'B' is the 2nd letter.

I am an expression of a deer mint.

'Honey' is a common term of endearment (assuming the 'a deer mint' = 'endearment' theory ala @seasnake).
