The Joy-Cons use bluetooth or a wired connection to communicate with the console, depending if they are physically connected to it or not.
dekuNukem has started RE on the protocols used [1].
Firmware
The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.
| Controller | 1.0.0 |
|---|---|
| Joy-Con Left (Blue) | flash dump |
| Joy-Con Right (Red) | flash dump |
The flash is in a patch-ram format. Tools for dealing with it are available [2]. A dump of the ROM region (taken while firmware was running) can be found here. Note this is the same SoC used on the other controller models, as well.
Left & Right Separate Joy-con
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

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.
| Color Name | Body HEX | Button HEX |
|---|---|---|
| Gray | #828282 | #0F0F0F |
| Neon Red | #FF3C28 | #1E0A0A |
| Neon Blue | #0AB9E6 | #001E1E |
| Neon Yellow | #E6FF00 | #142800 |
| Neon Green | #1EDC00 | #002800 |
| Neon Pink | #FF3278 | #28001E |
| Mario Red | #e10f00 | #280a0a |
