The SmartFade ML has RGB LED indicators that are factory-calibrated to a white mix. Due to manufacturing differences in LEDs, there may be a need to recalibrate the LED button colors on your console so that "white" is actually white. This can be done (as of software v2.0) in the [Setup] menu under the item [LED Calibration].
The following are the settings that have been found to give a good white depending on the version of LED that is in the console.
Option 1: Red: 255, Green: 195, Blue: 205
Option 2: Red: 255, Green: 180, Blue: 190
Option 3: Red: 255, Green: 217, Blue: 217
Option 4: Red: 255, Green: 210, Blue: 220
Note: If you reinstall software or go all the way through the diagnostics menu memory check, these settings will be lost and will need to be set again.
