Green Verditer, is shadowed with Copper-Green, and in the darkest places with Sap Green. Sap-Green, is only used to shadow other Greens. There are several other Greens as hath been treated of, which I shall here omit. Cerus, White-Lead or Flake-white, are shadowed which a small quantity of Black, mixt therewith, or a shadow is made with some Blue-Bice, and white. Thus having given you the shadows to every Colour; in the next place, I shall proceed to such Colours that set off best together. What Colours set off best together. REds set off well with Greens Yellows, Whites, and Blues; but best with Blues and Yellows. They set off not well with Purples, Blacks or Browns. Blues set off well enough with Yellows, Browns, Reds, Whites, and Blacks. They set off best with Reds, Browns, and Whites. But not well with Purples and Greens. Yellows set off well with deep Blues, Reds, Browns, and Purples; they set off not well with Whites, Blacks or light Greens, but best with Reds, and Blues. Greens set off well with Reds, Browns, and Purples; they set off best with Reds and Purples, but not well with Whites, Blacks and Blues. Browns set off well with no Colour, but worst with Black. Blacks set off well with any Colour, except Browns. Whites set off well with all Colours. How to make Changables. CHangables are such kind of Paintings whose Lights are of one Colour, and their shadows of another; which is very delight-ful to the Eye, by reason of the Variety of Colours therein used, according to the several Degrees of Light, which are commonly three; In the first whereof Simple White is used alone for the Light. In the first Degree White may be shadowed with faint Yellow, Pink mixt, Light Green, Light Blue, Light Purple, Light Ash-colour, Flame Co∣lour, Light Tawny, and Light Red. In the second Degree the Light Colours, that serve for shadows (in the first Degree where the Lights of Changables are,) White must be sha∣dowed in this sort, with deeper Colours, as with Purples, Straw-colour, Oaker, Sad Ash-colour, Tawny, Bice, Pink, Vermillion, Red-lead, and Spanish-brown. And in the third Degree those Colours which serve for shadows in the second Degree, are again shadowed with other deeper and darker, as Vmber, Lake, Indico, Smalt; and lastly, as White hightneth them, so doth Black shadow them. In the next place, I shall give you some direct∣tions for the Grinding and Washing of your Colours. Grinding of Colours. COlours are to be Ground upon a Peble-stone, or some other that is hard, for the hardest is the best; then Grind them with fair Water without Gum, and when they are very Fine Ground, put them upon a Chalk-stone to dry, and reserve them in Boxes, or Papers for your use. Washing of Colours. THe reason why Colours are to be washed, and not Ground, is because they are of so san∣dy, loose, and gravelly a Quality, and of so heavy, and Solid Bodies that they can hardly be reduced to the fineness by Gringding as is required; besides that way they presently become starved and dead; and Masticot and Red Lead becomes greasy, clammy, and utterly unserviceable. But to proceed. Take an Ounce or two of Read Lead, put it in∣to an Earthen-dish full of pure Water, stir it for a while together with a Spoon till the Water be all Coloured, then let it stand a little, and there will be on the Water a greasy Scum, which toge∣ther with the Water cast away, then fill the Ba∣son with Fresh Water, and stir it as before, till the Water be thick and troubled, which done, before it be half setled pour it out into another Dish, reserving behind in the other Bason, the Dregs and setling of the Colour, which cast away, for you are to seek not much, but good; if a Pound of it will yield 2 or 3 Shells of fine Colour, it is sufficient. The troubled, and Coloured Water be∣ing cast into the second Dish, put more Water to it, and wash it as the former, then let it settle until it be clean, and so pour off the Water, washing it again and again, if any Scum arise you may make 4 or 5 sorts, still pouring half the thick∣ned Water into other Dishes, and washing them as aforesaid; when you have washed it enough, and the Colour is quite setled, pour off the Wa∣ter, and let the fine Colour dry; then with a fine Feather take off the finest part of the Colour, re∣serving it for your curious Works, and the other for that which is more course. You must tem∣per them with Gum Water for your use, as afore∣said. What is said for washing Red Lead may be said for the washing all other Colours. Rules for the tempering of your Colours. 1 IN Tempering, or Mixing your Colours have a great care not to put your Pencils out of one Colour into another, for that will make them dirty, and Spoil them; for prevention of which, have by you at your working a Poringer, or Pan of Fair Water to wash your Pencils in, when you have done with any Colour, so that it will be clean to put into any other. 2. In Mixing your Colours, stir them about well in the Shell, with your Pencil, before you Mix them together, for the Thick is not good as well as the Thin, but let the Water be well Co∣loured, and all of a thickness; then pour them into a Shell together; but first pour in your light∣est Colour, by which you will know how much of the Sad will serve you turn. 3. In Mixing your Colours be careful that you make it not too Sad, for then it is hard to recover it without spoiling; therefore when you have oc∣casion to Mix any Sad Colour with those that are Light, put in but a little and a little of the Sad Colour, until you find it Sad enough for your 0
