1. Select a **non-catalyst** ingredient **C** for which you have already tested **C + A** and **C + B**.  It is OK if there was a reaction in those earlier tests.  Desert Paint Lab can work out the math.

1. In Desert Paint Lab, select ingredients as follows:

    1. **C**

    2. **A**

    3. **B**

1. Add the ingredients in your Pigment Lab _in exactly that order_.

1. Capture.

1. Record.

For clipped reactions, your **C** ingredient should be one that corrects for the clipped color.  Here are some suggested **C** ingredients for clipping correction:

Clip Color  | Clip Direction | Correction | Suggested "C" Ingredient

------------|----------------|------------|---------------------------

Red         | Low            | +Red       | Carrot (224) or Red Sand (144)

Red         | High           | -Red       | Silver Powder (16) or Toad Skin (48)

Green       | High           | -Green     | Red Sand (16) or Silver Powder (16)

Blue        | High           | -Blue      | Red Sand (24) or Clay (32) or Carrot (32) or Silver Powder (32)

In many cases, it may be easiest to go back and do these three-way tests after you have finished all of your other testing.

### Catalysts

For catalyst to catalyst reaction tests, follow the three-way instructions, as above.

### Finishing Up

When you're done testing your reactions, you can either use the built-in Pigment Lab simulator (`Window > Run Simulator`) to experiment with recipes, without dipping into your precious ingredient stocks.  Alternatively, you can export your reactions in PracticalPaint format.
