When I bought my longarm, I turned a "tool/storage" room into my quilting room. I had to clear it all out (and do something with all the junk), put in flooring, rework the exterior door threshold, hang mini blinds, etc. I really wanted to paint the room, but was running out of time and, mostly, energy. I had to make a run to Lowes for supplies and made a deal with myself. I decided I would check the clearance paint (miscolored paint) section and, if they had a nice blue (my favorite color) or green, I would buy it and paint the room; otherwise, I was done! I was actually hoping all the way there that they wouldn't have anything, but, wouldn't you know...they had a wonderful light, steely blue for just a few bucks!! (Oh, maaaannnn!!! LOL) I reluctantly pressed forward and am glad I did.
I really think that you should just pick a color that makes you happy and go for it. After all, it is your "happy place."
