The effects of color reconnection (CR) at colliders are revisited, with focus on recently developed CR models. The new models are compared with the LEP2 measurements for and found to lie within their limits. Prospects for constraints from new high-luminosity colliders are discussed. The novel arena of CR in Higgs decays is introduced, and it is illustrated by shifts in angular correlations that would be used to set limits on a potential CP-odd admixture of the 125 GeV Higgs state.
