Abstract Blue‐phase liquid crystals (BPLCs) possess unique 3D periodic chiral structures and extraordinary optical manipulation capabilities, demonstrating considerable potential in flexible displays, high‐security encryption, intelligent sensors. Despite lattice deformations of BPLCs widely exist various applications, there remains a challenge to understanding the quantitative relationship between different deformation modes resulting diffractive optics. Herein, universal simulation strategy is proposed based on spatial geometry modeling enable real‐time computation dynamic responses BPLCs. This framework systematically interprets predicts characteristics under both symmetric (governed by dopant concentration) asymmetric (induced phase separation or component dispersion). Differentiated nonlinear effects are revealed for these Kossel diffraction analysis. Furthermore, anisotropic modulation surface/sectional structural colors (photonic bandgaps) angle‐dependent control over full light field demonstrated tailoring interplanar spacing facet orientation within symmetry constraints. study establishes theoretical foundation designing next‐generation BPLC‐based photonic devices, including holographic all‐optical switches, integrated waveguides, lasing systems.
