### Clipped? Huh?
Occasionally, you will see a warning dialog that informs you that a "Reaction clipped." That means that one or more of the color components moved outside of the testable range. This makes it impossible to calculate the reaction from these two ingredients.
You can solve this by doing a three-way test.
1. In your clipped reaction, let's call your **1st** ingredient **A** and your **2nd** ingredient **B**.
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. Capture.
1. Record.
For clipped reactions, your **C** ingredient should be one that corrects for the clipped color. For example, if your reaction clipped low on blue, consider using Copper or Earth Light for your **C** ingredient, because those are very blue. On the other hand, if your reaction clipped high on red, consider using Toad Skin as your **C** ingredient, because it is very low on red.
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 | High | -Red | Silver Powder (16) or Toad Skin (48)
Green | Low | +Green | Earth Light (240) or Copper (192)
Green | High | -Green | Red Sand (16) or Silver Powder (16)
Blue | Low | +Blue | Earth Light (224) or Copper (192)
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.
## Known Issues
### Slowness
If you are running on a multi-screen system, or a very high-resolution screen, you may find that Desert Paint Lab is rather slow in determining paint reactions. That's because you have a lot of screen real-estate to scan, to look for the Pigment Lab dialog. You can speed up the scanning process by ensuring that your Pigment Lab Dialog is as far to the upper-left of the screen as possible.
