AmFmCodes
These are 32-bit values used by the Joy-Con firmware to represent combinations of amplitude/frequency pairs for vibration.
Unpacking
The Joy-Con firmware receives vibration data packed as VibrationAmFmPackTag from output reports. Depending on the packing format, these tags are then converted to an array of AmFmCodes as follows.
AmFm5BitCodes
Converted from VibrationAmFmPackFormatOne, VibrationAmFmPackFormatTwo or VibrationAmFmPackFormatThree.

Colors
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.
