Acteon particolor is a species of sea snail, a marine gastropod mollusc in the family Acteonidae.

(Original description) The small, short shell is rotund and smooth.

The about four visible whorls are moderately rounded and separated by a distinct suture.

The outer lip is thin, sharp and arcuate, rounding evenly in front to the slightly thickened strongly twisted columella behind which is a minute chink.
