Red and Yellow make Orange Tawny.

Red with a little White makes a Carnation.

Red with an Eye of Blew, makes a Purple; and by these simple Compositions
again Compounded among themselves, the Skilfull Painter can produce what
kind of Colour he pleases, and a great many more than we have yet Names
for. But, as I intimated above, 'tis not my Design to prosecute this
Subject, though I thought it not unfit to take some Notice of it, because
we may hereafter have occasion to make use of what has been now deliver'd,
to illustrate the Generation of Intermediate Colours; concerning which we
must yet subjoyn this Caution, that to make the Rules about the Emergency
of Colours, fit to be Relied upon, the Corpuscles whereof the Pigments
consist must be such as do not Destroy one anothers Texture, for in case
they do, the produced Colour may be very Different from that which would
Result from the Mixture of other harmless Pigments of the same Colours, as
I shall have Occasion to shew ere long.

_EXPERIMENT XIII._

It may also give much light to an Enquirer into the Nature of Colours, to
know that not only in Green, but in many (if not all) other Colours, the
Light of the Sun passing through Diaphanous Bodies of differing Hues may be
tinged of the same Compound Colour, as if it came from some Painters
Colours of the same Denomination, though this later be exhibited by
Reflection, and be (as the former Experiment declares) manifestly
Compounded of material Pigments. Wherefore to try the Composition of
Colours by Trajection, we provided several Plates of Tinged Glass, which
being laid two at a time one on the top of another, the Object look'd upon
