Highlights of top-quark properties measurements at the ATLAS experiment

The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronizes, this gives a unique opportunity to probe the properties of pseudo-bare quarks. This proceeding focuses on a few recent precision measurements of top-quark properties in top-quark pair events by the ATLAS Collaboration. Among these is the measurement of color flow and measurement of spin correlations in $t\bar{t}$ pair production. Measurements of the top-quark mass and searches for rare top-quark decays are also presented.
