Applying the inverse scattering transform to study a focusing two-component Hirota equation with nonzero boundary conditions at infinity. Through the spectral problem and the adjoint spectral problem, the analyticity properties and symmetry relations of the eigenfunctions and scattering coefficients are systematically investigated. Based on these properties, the discrete spectrum is comprehensively characterized, producing three types of discrete eigenvalues. The asymptotic behavior of the eigenfunctions and scattering coefficients is explored in detail. Furthermore, the inverse scattering problem is formulated through a suitable matrix Riemann-Hilbert problem, and the trace formula along with the reconstruction formula for the potential function are derived. The reflectionless condition facilitates the successful construction of N-soliton solution. Finally, various types of solitons are obtained by considering different types of discrete eigenvalues and their combinations, and the interactions of these solitons are demonstrated.
