Natural pigment vermilion remains standard in oil vehicles.

Famous quotes containing the words modern and/or day:
“It is unheard-of, uncivilized barbarism that any woman should still be forced to bear such monstrous torture. It should be remedied. It should be stopped. It is simply absurd that, with our modern science, painless childbirth does not exist as a matter of course.... I tremble with indignation when I think of ... the unspeakable egotism and blindness of men of science who permit such atrocities when they can be remedied.”
—Isadora Duncan (1878–1927)
“The day is always his, who works in it with serenity and great aims.”
—Ralph Waldo Emerson (1803–1882)
