Olive green may be made by adding to blue-green either red or preferably yellow brown. This addition should be made a little at a time with frequent tests, a suggestion applicable to all color mixing.
Tan is obtained by mixing yellow and yellow brown. An added tinge of blue or green gives pongee.
Gold contains much yellow with certain smaller amounts of red and blue. But it might be difficult to control the addition of these colors, so it is better to start with much yellow and add a little at a time orange and blue green.
For burnt orange add yellow brown to orange.
For turquoise add to blue a little yellow, or preferably blue green.
For old rose add to dilute red a tinge of blue or preferably purple.
Taupe is a gray thrown off, usually with purple, but sometimes with red or yellow or blue.
Salmon is formed by adding to yellow some orange and a tinge of brown.
Any dyeing over old color must be considered as a mixing of the new color with the old, which manner of thinking will help in choosing the dye necessary for a desired effect. For example, a green cloth is to be dyed black. There should be two dyeings, the first a red to neutralize the green, the second a black to intensify the neutrality. Likewise a red cloth becomes black by dyeing first green and then black.
Over a light yellow purple may be dyed, the result will be a grayed purple. Over a strong yellow much purple will be required and the result will be a very much grayed purple approaching if not becoming a purple black.
