We propose generalized equilibria of a three-dimensional color-gradientlattice Boltzmann model for two-component two-phase flows using higher-orderHermite polynomials. Although the resulting equilibrium distribution function,which includes a sixth-order term on the velocity, is computationallycumbersome, its equilibrium central moments (CMs) are velocity-independent andhave a simplified form. Numerical experiments show that our approach, as in Wenet al. [Phys. Rev. E 100, 023301 (2019)] who consider terms up to third order,improves the Galilean invariance compared to that of the conventional approach.Dynamic problems can be solved with high accuracy at a density ratio of 10;however, the accuracy is still limited to a density ratio of $1\,000$. Forlower density ratios, the generalized equilibria benefit from the CM-basedmultiple-relaxation-time model, especially at very high Reynolds numbers,significantly improving the numerical stability.
