Translucents are oil based, but wash with water, and should be able to wash nicely off of brushes.
Any translucent color may be used to antique. The following colors are most popular because they are neutral: S-2 Mocha, S-9 Gray, S-17 Black, S-28 Brown, S-23 Mediterranean, and S-35 Cocoa. .
You can also use multiple colors on different parts of your project. An example might be a piece where S-42 Morning Glory might be great for your sky, but with logs and/or rocks at the bottom, you may wish to use S-28 Black-Brown.
We also recommend using a stiff bristled brush. The firm bristles do a better job getting into the deep crevices of the pieces
Any of the translucent colors can be used to create your own custom colors.
