  Skyrmions are promising for the next generation of spintronic and magnonic
devices, but their zero-field stability and controlled nucleation through
chiral interactions remain challenging. In this theoretical study, we explore
the potential of moir\'e magnetic heterostructures to generate ordered skyrmion
lattices from the stacking-dependent magnetism in 2D magnets. We consider
heterostructures formed by twisting ultrathin CrBr_3 films on top of CrI_3
substrates, assuming a moderate interfacial Dzyaloshinskii-Moriya interaction.
At large moir\'e periodicity and appropriate substrate thickness, a moir\'e
skyrmion lattice emerges in the interfacial CrBr_3 layer due to the weaker
exchange interactions in CrBr_3 compared to CrI_3. This lattice is then
projected to the remaining layers of the CrBr_3 film via emergent chiral
interlayer fields. By varying the pristine stacking configurations within the
ultrathin CrBr_3 film, we realize layered ferromagnetic and antiferromagnetic
skyrmion lattices without the need for a permanent magnetic field. Our findings
suggest the possibility of creating colorful skyrmion lattices in moir\'e
magnetic heterostructures, enabling further exploration of their fundamental
properties and technological relevance.
