What does colourableness mean?
Colourableness is a rare noun meaning the quality or state of being colourable. Its most characteristic use is in legal or argumentative English: a claim, defence, or stated reason is colourable when it appears credible, legitimate, or plausible even if its substance is doubtful. The noun can therefore refer to that persuasive appearance rather than to factual truth. A second, literal sense denotes the capacity of something to receive or take on colour, although this use is much less common. Because the word is formed from colourable plus -ness, it is not especially common even where the underlying adjective is understood. British spelling writes colourableness, while American English normally uses colorability. The term is chiefly encountered in formal legal writing, dictionaries, and discussions of the difference between appearance and reality. In ordinary prose, colorability or, where appropriate, plausibility, credibility, or capacity to take colour will usually be clearer and more natural.

Where does colourableness come from?
Colourableness is an English noun formed from colourable and the noun-forming suffix -ness. Colourable combines colour with -able and is used both for something able to take colour and, especially in legal English, for something presenting a plausible appearance. The colour element ultimately comes through Old French couleur from Latin color, while the legal sense develops from the idea of giving a claim an apparent, potentially misleading, air of truth or legitimacy.
