General advice is smart switches, dumb bulbs. Switches mean that you can control the light without getting out your phone, or whatever it is you use to control the bulb. Sure HA can talk to many bulbs, but only if the switch is on. Guests will not have the ability to control your bulbs - either there is too much work to install an app for a short stay, or the system is a security nightmare (often both). Use a smart switch because they have a control on the wall that guests can use to get what they want done without having to worry about apps.
Most often you can choose bulbs with the right color temperature, but if not some dimable bulbs change color temperature. If this is not good enough two lights: a general room like, and a separate special effects light, don't combine them (HA can control both, but they are separate systems generally not used at the same time)
China has been planing to reunite with Taiwan for decades, and they are clearly building a military capable of that. The US has committed to protecting Taiwan. That is the US has been planning war with china since not long after WWII. It hasn't happened yet, it may never happen, but it is planned for and one of the more likely wars the US could get involved with.
If your country doesn't have a plan to go to war with every other country in the world (separately) your military leaders are incompetent. Most counties far away are very low risk and so the plans don't have to be well thought out, but you should have at least the start of a plan. The more likely war is the better you plans should be.
