I have a color bulb device, Third Reality Night Light. I can change the color using Hue and Saturation. But the ColorName seems to be totally random and no relation to the actual color. For example, right now the light is White. ColorName says Red.
Without looking at the device I would guess that the ColorName is only provided as a means of quickly selecting a new color and is not sync'ed with changes made using Hue and Saturation (partially because many Hue/Saturation combos are not named).

I have had similar problems with Sengled Smart LED Light Strips.
The colorName attribute is made up in the driver, based on the hue/saturation or x/y
Typically, it is not a parameter sent by the device , at least not in the Zigbee and Matter protocols.
So what the colorName is in the Current States, depends on the driver used - how well the driver handles the switching between the colorTemperature mode and the RGB modes.
I kinda figured it was. It appears to only be an Attribute and not a Capability. (If I got that right). Be nice if you can set the color using that, but no.
I know in RM you can select a color. But it isn't very accurate. For example, I can select red and it comes out more Orange. But If I set the Hue and Saturation I can get Red.
I remember that I had a hard time matching the color names in the Matter Bridge package, as you can change the color and the CT/RGB mode not only from Hubitat, but also from the other systems - Apple Home, Tuya, Aqara, etc.. using their own color selection wheel controls.
I actually deleted it from Apple Home as I didn't need it there. But before I deleted it I played around with the color and it wasn't much use.
I end up in the device itself, in HE, playing with the Hue and Saturation until I get the colors I want. Then make my own table to use as needed.

Have in mind, that ThirdRelity products being designed in a facility located next to Tuya's in Shenzhen, may have the same bugs related to the color presentation.
There is one well known bug in most of the Tuya color bulbs/RGB controllers, affecting the red color. The 'redFix' patch is widely used in Zigbee2MQTT for most of the Tuya bulbs.
I have an Osram LIghtify bulb that the Red seems to work the same as this Third Reality Device. Hue of 0, saturation of 100.
In any event, my main question was on the ColorName. But in reality it's not of much use for anything anyway. Just curious where it got it's value from.
