Color Masking

AgBr films could be made in the same manner using various bromo-alco-hols. AgBr is colorless but is usually slightly brownish due to photolytic formation of small particles of metallic silver (this occurs much more strongly if deposition is carried out in room light, but formation of some brown coloration is stiU noticeable even if deposition is carried out in the dark). This coloration masked the optical absorption, which occurs mainly in the UV for AgBr. For bromides, triethanolamine was not needed. 

In Hofmann s account, other features of interest to the schizophrenia connection are the transmogrification of Mrs. R., the lady next door, who turned into a malevolent insidious witch with a colored mask, and the grotesque threatening forms that familiar objects and furniture assumed.

The faces of those present appeared like grotesque colored masks strong agitation alternating with paresis the head, body and extremities sometimes cold and numb a metallic taste on the tongue throat dry and shriveled a feeling of suffocation confusion alternating with a clear appreciation of the situation. 

The work of Iida et al. (84,85,86) on stabilization by complementary color development has been extended now to include the use of various color-masking agents that apparently can prevent the formation of excessive amounts of highly colored polyene-metal complexes (HO). 

Thousands of years ago, before there were craft stores and manufactured paints, people looked to the earth for their craft materials. Art on cave walls and colorful masks and clothing were decorated with paints made from crushed seeds, plants, water, oils, and dirt. Nature provides us with many tools for making art, and today the earth still provides us with materials to create paints.
