Please forgive me, if it’s impolite to mention here, but as color temperature control on left/right button press was requested multiple times here, I feel I should mention that - based on this great blueprint - I wrote a blueprint that can control color temperature (not full rgb color range) for white spectrum and rgb color light entities.
Also note, that there are some differences to this blueprint, for example, it does not feature the convenient target selector so only a single light entity can be controlled.

If you use an entity selector instead of the target selector in this blueprint, you can access that entities rgb_color attribute and probably from that calculate your next rgb color value to set the light entity to in order to achieve a color cycle effect. However, you loose the ability to control multiple entities or areas with one blueprint.
