  Let $G$ be an abelien group, $\epsilon$ an anti-bicharacter of $G$ and $L$ a
$G$-graded $\epsilon$ Lie algebra (color Lie algebra) over $\K$ a field of
characteristic zero. We prove that all $G$-graded, positive filtered $A$ such
that the associated graded algebra is isomorphic to the $G$-graded
$\epsilon$-symmetric algebra $S(L)$, there is a $G$- graded $\epsilon$-Lie
algebra $L$ and a $G$-graded scalar two cocycle
$\omega\in\mathrm{Z}_{gr}^2(L,\K)$, such that $A$ is isomorphic to $
U_\omega(L)$ the generalized enveloping algebra of $L$ associated with
$\omega$. We also prove there is an isomorphism of graded spaces between the
Hochschild cohomology of the generalized universal enveloping algebra $U(L)$
and the generalized cohomology of color Lie algebra $L$.
