Note 294 — Chapter V
Reading edition
Semper gives us an account of iodine colours. Some, he says, were extracted from sea-weeds, green and yellow; the purples, when finest, from the shell-fish. The Phœnician coasts gave the best purples; those of the Atlantic the best blacks and browns. And thus he completes the scale of iodine colours. See Semper, “Der Stil,” i. p. 206.
