I think you should have one.
There have been a few things, like this tree, that I thought on through the years, but finances and my "better judgement" kept me from pursuing them. After my brother passed, something in me decided (not all at once but...).... that a few of those things I ALWAYS wanted.... I was going to have ! Life is too short not too. This is one of them.
There IS something magical about those color wheels for sure.
