So this could just be a really stupid question. My Lupora can *Can Re-Generate All Colors* and I'm taking a long time to decide how she should look. I'm worried that she won't be able to change colours if I leave it days/weeks to decide. How long does the regenerating option last for? Forever or just a little while?

It's a perfectly valid question. Your Lupora will continue to say that until you finalize the changes.

In short, forever.

I have Lunes that can still be regenned, and their revamp was a couple of months ago (I think). If you're having trouble coming up with colors, I'd play around in the generator first, and then save them until you're ready and know what colors to place on her.

Added a short note on this to the Regen guide

Thank you, you have really put my mind at ease. I will be sure to take my time and fully design her new colours in the generator before making it final. I already have about 5 versions of basically the same colours, I just have to choose and finish up!

No problem at all! Getting the right look takes time, so no rush! Good luck choosing a fitting coloration for her, and I look forward to seeing her finalized look. :)
