Matching Color at www.japanese-home-gardens.com

In matching colors, it is advisable to look at the original and the new mixture through a "color window." This is merely a hole of about ll/2 inches diameter cut out of a sheet of white paper. The two colors should be placed directly adjoining each other and compared through the hole. The white paper prevents either color from being influenced by any nearby color and the differences in hue, chroma, and tone of the two colors are easily distinguishable.

There are two basic approaches to the use of allografts and xenografts. One is through modification of the recipient's immune mechanism (a process known as immunosuppression) to allow donor Tissue to become established and hopefully accepted as "self" by the recipient's body. The other approach is by matching tissues of potential donor and recipient, as is done routinely in blood typing. Tissue matching is based on the assumption that there are underlying biochemical similarities in the tissues of members of a species; the closer the matching, the greater the chance of success.

Suggestions for mixing paint colors. There are no scientific formulas for mixing pigments to produce other colors. One cannot state either what quantity, volume, or weight of paint to use to obtain a desired result. This is due to the fact that the chemical ingredients of certain pigments have stronger tinting values than others, so that relatively less of those pigments must be used in mixtures. The production of colors by pigment mixtures must be done by the trial and error method of visual examination. In trying to obtain a certain color by a paint mixture, the decorator is usually matching another color or producing axolor that will be suitable for some part of a room or one that will harmonize suitably with the other hues of a tentative color scheme.
