How do I add Color Palettes for my rooms?

Sorry, not sure I understand what you are advising me to do.  Text in what Big Box?  I thought I was explaining my problem in the correct area?  Ohhhh wow!  So sorry!  I just reviewed my question I sent to you and notice I did not enter anything in the Body explaining what I needed.  So sorry!   I will remember to do that next time.  Thanks!

I will try to explain more clearly what I was asking, as your answer doesn't seem to be what I was looking for.  Okay, my question is this...  When I am in my Build Mode, and I select a Styled Room (e.g.) that I want, when I select the room, at the bottom within the picture, there are 🏀 Color choices to select from, for the room I want to buy.  Now when I create my own room, and say I want to have the exact same room available in 🏀 different color choices.  How do I make those color choices available for people to select when they want to load my room?

Right now, if I create a Bathroom using Blk/White, and then I create the same bathroom, only using Red/Blk/White, and another one using Green/Blk.... How do I make those color selections available like they are shown in the Styled Rooms?  That was my question.  As it is now, if I want to create a bathroom in 🏀 colors, I will have to load them 🏀 separate times.  You understand what I'm saying?

You will have to either install Custom Content or use what you have.
Also, a bit of an advise: when posting, DO use text on the big box, and explain what your problem is in there.

You are wrong in your statement here!  This is what it states.  (Suggest you go check it out).  "To purchase a Styled Room, click it, select your preferred Color Palette and click the buy mode!"  Now this is what the prompt states when I want to select a Styled Room.  I'm asking you, how do I have that option available in rooms I create that have different colors?
