Well, I'd have to be one who can't agree on that, because Free just meant not enslaved or bound...and a former slave who was freed would then be a Free Person..whether Free Black or Free Colored..
Free Colored meant there was some African blood...
I have not personally researched this yet, but found it on another site, so am quoting it here:
"1866-- “Every person having one-fourth or more of
negro blood shall be deemed a colored person, and every person not a
colored person having one-fourth or more of Indian blood shall be
deemed an Indian.” (_Acts of the Assembly_, 1865-1866, pp. 84-85)

1910--Virginia defined a "colored person" as anyone with 1/16th
African ancestry. (_Acts of the Assembly_, 1910, p. 581)

1924--Virginia’s Racial Integrity Law defined a “white person” as one
“who has no trace whatsoever of any blood other than Caucasian.”
Except . . . to account for the few Virginia elites who traced their
ancestry to Pocahontas, the law allowed that "persons who have one-
sixteenth or less of the blood of the American Indian and have no
other non-Caucasic blood shall be deemed white persons." Notice, this
law defines white people (and Pocahontas's descendants). (_Acts of
the Assembly_, 1923-1924, p. 468)

1930--
"Every person in whom there is ascertainable any Negro blood shall be
deemed and taken to be a colored person, and every person not a
colored person having one-fourth or more of American Indian blood
shall be an American Indian; except that the members of Indian tribes
living on reservations allotted them by the Commonwealth having one-
fourth or more of Indian blood and less than one-sixteenth of Negro
blood shall be deemed tribal Indians so long as they are domiciled on
such reservations." (_Acts of the Assembly_, 1929-1930, pp. 96-97)"
