Lambda light effects with last selected color

Hello all,
for those who want a simple question: skip the next paragraph and go to TL;DR :wink:

For our guest room I would like to have two PIR sensors and two addressable LED strips under the bed. If someone stands up at night, the PIR sensor triggers a simple activation of the LED strip on the side. This works fine at the moment, but I want an effect that lights up one LED after the other, just like the wipe effect, but not continuously. The wipe effect from the Light Component works good too, but I do not want a color, instead it should light up with the last selected color from the user, just as when you switch on the light.

TL;DR: Is there a way to access the last color and brightness of the LED strip inside a lambda?

THX in advance!

Looking for exactly this! Did you ever find a way to do this?
