Definition
A Latin term meaning "by color of" — that is, by the outward appearance or pretext of some right, office, or estate. Used in pleading and substantive law to describe an action taken under a claimed or supposed legal authority that is either defective, disputed, or asserted in bad faith. The term operates as a qualifier: it signals that a person is acting under the semblance of right rather than right itself.
Colore appears most frequently in two legal contexts:
1. Colore officii — by color of office. Describes a wrongful act committed by a public officer under the guise of official authority. The officer invokes their position to do something the law does not actually permit.
2. Colore tituli — by color of title. Describes possession of land held under a written instrument or claim that appears to convey title but is legally defective. Central to adverse possession doctrine, where color of title can affect the scope and computation of a claim.
In both uses, the Latin phrase flags a gap between the appearance of legal authority and its actual existence.

Common Language
Modern common usage (Wiktionary): An obsolete spelling of "color."
Historical common usage (Webster's 1913): "Color" in ordinary English referred to hue or outward appearance; by extension, a pretext or semblance.
The legal term colore is not the same as the English word "color" in either its visual or colloquial sense. In law, colore carries a specific technical meaning — acting under a pretextual claim of right — and almost always signals legal defect or overreach. A researcher encountering colore in a historical document should not read it as a general reference to appearance or pretext in the lay sense, but as a term of art pointing to a specific legal relationship between claimed authority and actual authority.

Common Confusion
Colore is often encountered only as a fragment of a longer Latin phrase — colore officii or colore tituli — and researchers unfamiliar with the standalone term may not recognize it as a discrete legal concept. The word alone does not specify which context applies; the noun following it (officii, tituli, etc.) supplies the operative meaning. Treating colore as mere decorative Latin, or assuming it means only "by color of title," risks missing the broader doctrinal territory the term covers.

Why It Matters in Research
Researchers working in historical sources — particularly pre-twentieth-century pleading records, equity opinions, and land title disputes — will encounter colore frequently as a signal phrase. Several navigational points apply:
First, colore in a pleading often signals that the drafter is conceding a defect in the underlying right while arguing the defendant acted as if valid authority existed. Recognizing this structure is essential to understanding the legal theory of the document.
Second, in adverse possession research, the phrase colore tituli (or "color of title") can significantly affect the outcome of a claim. In many jurisdictions, adverse possession under color of title — even defective color — was treated differently than naked possession, often allowing the claimant to tack to the boundaries described in the defective instrument rather than only the land actually occupied. Sources that use colore without fully explaining this procedural consequence can mislead researchers working on title chains.
Third, colore officii is a distinct line of authority relevant to civil rights and official liability research. The phrase appears in historical common law cases involving abuse of office, and its conceptual descendants survive in modern civil rights doctrine under 42 U.S.C. § 1983 ("under color of" state law). A researcher tracing the lineage of the "under color of" standard in civil rights law will need to work through the colore officii tradition in the common law sources.
Fourth, Burrill's entry is spare. Researchers should not treat the dictionary entry as a complete account of the term's usage — it is a pointer, not an analysis.

Historical Dictionary Support
Burrill's Law Dictionary defines colore simply as "by color (of a supposed estate or right)" and notes it is "usually taken in a bad sense," citing Townshend on Pleading. This characterization is consistent with the term's function across historical sources: colore nearly always marks an action as taken under defective or pretextual authority, not genuine right.
The brevity of Burrill's entry reflects a common limitation in nineteenth-century legal dictionaries — Latin terms of art were often treated as self-explanatory to a trained reader, with the operative content left to the compound phrases (colore officii, colore tituli) rather than the root word. Researchers relying solely on the root entry will need to consult those compound entries for the substantive doctrine. Burrill covers colore officii separately, and the fuller content lives there.
Historical dictionaries generally agree on the "bad sense" characterization, though some property-law sources give colore tituli a more neutral treatment — recognizing that a defective instrument might support an adverse possession claim without implying wrongdoing by the claimant. The pejorative connotation is strongest in the officii context, where abuse of power is the operative concern.

Jurisdictional Note
The procedural significance of colore tituli in adverse possession varies considerably across American jurisdictions. Some states treat color of title as required or significantly advantageous; others allow adverse possession by naked possession alone, making colore tituli less determinative. Researchers working on title disputes should not assume a universal rule from historical sources.
