* *Color code multiplier:* The signatures associated with color codes can be more inclusive, because false positives are less likely.  Also, the color swatches used with color codes may be somewhat reflective, which requires a more inclusive signature.  The *Color code multiplier* is multiplied by the corresponding *Signature range* (in the "Signature Tuning Tab":/projects/cmucam5/wiki/Signature_Tuning_Pane) to create the signature range for the color code.

* *Color code mode:* This parameter sets the behavior of color codes, including enabling/disabling.  Hovering the mouse over the parameter will provide information on the available settings.

*Enabled:* Color codes are enabled, normal mode.
11 12 Rich LeGrand
*Disabled:* Color codes are disabled.

*Color codes only:* Only color codes are reported.  Objects that match non-color-code signatures will not be reported.

*Mixed:* This is the same as normal color code mode, but Pixy will also report color-code signatures that aren't part of color codes.  (Normally, Pixy only reports color-code signatures that are part of color codes -- 2 or more color-code signatures that are close together.)

* *Signature teach threshold:* This parameter applies when you are teaching Pixy a signature using the button-push method.  It allows you to adjust how inclusive Pixy is when determining which pixels are part of the object you are trying to teach.  You can find more information "here":/projects/cmucam5/wiki/Some_Tips_on_Generating_Color_Signatures_2.
