African American women sometimes have trouble finding a foundation that matches their skin tone because many popular foundations have yellow undertones, which can look chalky and ashy on women of color.
Soy candles produce less soot - that dark, ashy substance that coats walls, ceilings is a particulate matter made up of carbon and is dangerous to human lungs.
The deeper tints are, however, peculiar to the nuptial plumage, or are only to be faintly traced at other times, so that in winter the adults - and the young always - have a much plainer appearance, ashy-grey and white being almost the only hues observable.
The colours range from deep black to pure white, passing through chestnut or bay, and many tints of brown or ashy-grey, while often the feathers are more or less closely barred with some darker shade, and the black is very frequently glossed with violet, blue or green - or, in addition, spangled with white grey or gold-colour.
The original material was a fine clay, sometimes with more or less of sand or ashy ingredients, occasionally with some lime; and the bedding may be indicated by alternating bands of different lithological character, crossing the cleavage faces of the slates, and often interrupting the cleavage, or rendering it imperfect.
