Hue light intermittently reports incorrect supported_color_modes

[Mariusthvdb]

The problem

discovered by using custom integration Powercalc, and because the error is mentioning that integration as logger, I reported there: https://github.com/bramstroker/homeassistant-powercalc/issues/1975

However, author mentions this:

Hi Marius,

light.dorm_ceiling_panel: Lookup table not found (model: LTC016, color_mode: brightness)

This means the light was actually on color_mode brightness at a particular point in time, Powercalc than tries to load the corresponding LUT file, but it can't because there is no available for brightness mode. It should never be in that color mode, because it's also not in the supported_color_modes of the light:

supported_color_modes:

• color_temp This is a bug in the Hue integration. I think I noticed Marcel about that some time ago, but I don't think anything has been done about that.

You might create another bug report on HA core tracker to report this issue, and get traction on getting this solved.

Also saw this developer blog post: https://developers.home-assistant.io/blog/2024/02/12/light-color-mode-mandatory

color mode validation is getting more strict (finally). So the scenario reported in the issue will also cause the core warning, and stop the light to work in the future.

This issue should have been fixed a while ago, just forgot to update here. There is one more issue remaining for grouped lights but that one is tracked in a different issue.
