523. _Sky-blue Bonnet._—Blue colour reflected on the skin is very feeble, except on the temples; wherever the blue parts are contiguous to parts feebly illuminated by daylight, the latter will appear slightly orange. 524. _Orange Bonnet._—Orange colour reflected on the skin is very feeble, except on the temples; wherever the parts are contiguous to parts feebly illuminated by daylight, the latter will appear slightly blue. 525. It is evident, then, from these experiments, that a coloured bonnet produces much more effect by virtue of contrast, arising from juxtaposition with the flesh tints, than by the coloured reflections which it imparts to them. 526. Let us now see what advantage the painter can derive from the preceding observations, when he prescribes a bonnet to a model, belonging either to the light-haired or to the black-haired type. FAIR-HAIRED TYPE. 527. A black bonnet with white feathers, with white rose or red, suits a fair complexion. 528. A _lustreless white bonnet_ does not suit well with fair and rosy complexions. It is otherwise with bonnets of gauze, crape, or lace; they are suitable to all complexions. The white bonnet may have flowers, either white, rose, or particularly blue. 529. A _light blue bonnet_ is particularly suitable to the light-haired type; it may be ornamented with white flowers, and in many cases with yellow and orange flowers, but not with rose or violet flowers. 530. A _green bonnet_ is advantageous to fair or rosy complexions; it may be trimmed with white flowers, but preferably with rose. 531. A _rose-coloured bonnet_ must not be too close to the skin; and if it is found that the hair does not produce sufficient separation, the distance from the rose colour may be increased by means of white, or green, which is preferable. A wreath of white flowers in the midst of their leaves has a good effect. 532. I shall not advise the use of a light or deep red bonnet, except when the painter desires to diminish too warm a tint in the complexion. 533. Finally, the painter should never prescribe either yellow or orange-coloured bonnets, and be very reserved in the use of violet. TYPE WITH BLACK HAIR. 534. A _black bonnet_ does not contrast so well with the general appearance of the type with black hair as with the other type, yet it may produce a good effect, and receive advantageously accessories of white, red, rose, orange, and yellow. 535. A _white bonnet_ demands the same notice as that, concerning its use, in connexion with the blonde type (528), except that for brunettes it is better to give preference to accessories of red, rose, orange, and yellow, rather than of blue. 536. Bonnets _of rose-red or cherry-colour_ are suitable for brunettes, when the hair separates, as much as possible, the bonnet from the complexion. White feathers accord well with red; and white flowers, with abundance of leaves, have a good effect with rose.
