Original sentence: In U.law, the term color of denotes the “mere semblance of legal right”, the “pretense or appearance of” right; hence, an action done under color of law colors (adjusts) the law to the circumstance, yet said apparently legal action contravenes the law
Edited sentence: Color of is a legal term meaning "pretense or appearance of" some right; in other words, 'color of', as in 'color of law', means the thing colors (or adjusts) the law; however, the adjustment made may either be lawful or it may merely appear to be lawful
