colourable

Doth the master make any bargaine, or dispatch that pleaseth not? it is immediately smothered and suppressed, soone after forging causes, and devising colourable excuses, to excuse the want of execution or answer.

This matter, however, is not itself coloured, but is only capable of exhibiting colours, by the addition of other matters : and hence we have ventured to call it the colourable, rather than the colouring parts of the plant, by which we merely indicate its property of becoming coloured, but not its actual possession of colour.
