  We develop a calculational scheme in Coulomb and temporal gauge that respects
gauge invariance and is most easily applied to the infrared asymptotic region
of QCD. It resembles the Dyson-Schwinger equations of Euclidean quantum field
theory in Landau gauge, but is 3-dimensional. A simple calculation yields a
color-Coulomb potential that behaves at large $R$ approximately like $V_{\rm
coul}(R) \sim R^{[1-0.2(d-1)]}$ for spatial dimension $1 \leq d \leq 3$. This
is a linearly rising potential plus a rather weak dependence on $d$.
