AS for _Colour_, it is the same with Body: for surely, there is no such thing in Nature, as a Colourless Body, were it as small as an Atom; nor no such thing as a Figureless Body; or such a thing as a Placeless Body: so that Matter, Colour, Figure, and Place, is but one thing, as one and the same Body: but Matter, being self-moving, causes varieties of Figurative Actions, by various changes. As for Colours, they are only several Corporeal Figurative Motions; and as there are several sorts of Creatures, so there are several sorts of Colours: but, as there are those, Man names Artificial Creatures; so there are Artificial Colours. But, though to describe the several Species of all the several sorts of Colours, be impossible; yet we may observe, that there is more variety of Colours amongst Vegetables and Animals, than amongst Minerals and Elements: for, though the Rain-bow is of many fine Colours; yet, the Rain-bow hath not so much Variety, as many particular Vegetables, or Animals have; but every several Colour, is a several Figurative Motion; and the Brighter the Colours are, the Smoother and Evener are the Figurative Motions. And as for Shadows of Colours, they are caused when one sort of Figurative Motions is as the Foundation: for example, If the Fundamental Figurative Motion, be a deep Blew, or Red, or the like, then all the variations of other Colours have a tincture. But, in short, all Shadows have a ground of some sort of dark Figurative Motions. But, the Opinions of many Learned Men, are, That all Colours are made by the several Positions of Light, and are not inherent in any Creature; of which Opinion I am not: For, if that were so, every Creature would be of many several Colours; neither would any Creature produce after their own _Species_: for, a Parrot would not produce so fine a Bird as her self; neither would any Creature appear of one and the same Colour, but their Colour would change according to the Positions of Light; and in a dark day, in my opinion, all fine coloured Birds, would appear like Crows; and fine coloured Flowers, appear like the Herb named Night-shade; which is not so. I do not say, That several Positions of Light may not cause Colours; but I say, The Position of Light is not the Maker of all Colours; for, _Dyers_ cannot cause several Colours by the Positions of Light.
