  We have developed a new chromatic compensation scheme for the electron storage ring with two low-beta interaction regions in the electron-ion collider. The hybrid scheme consists of modular chromatic matching of periodic systems and beamlines. The first-order chromatically matched solutions are linearly parameterized with the local linear chromaticities that control the higher order chromatic beatings. The parameterization enables an efficient optimization of dynamic aperture. As a result, we successfully achieve the 1% design criterion for the momentum aperture in the ring.
