I can't work out how this could actually work (if your smart color changing lights are just paired with regular switches).

1. It's midday, your lights are bright and blue 2. You turn the switch off. The bulb (and ESP) no longer has power. 3. It's 9pm; you turn the light on.

Would you not get bright blue light for a second or two until it had a chance to sync? You can get timely local execution with something like Tasmota but it has no consistent internal clock, so you're at least one network hop away from it taking proper state.
