Sounds good, but the "ideal" state so many of us hope to attain is to become completely transparent, so as not to be even noticed, in order for God's light to shine through us unimpeded. In other words, we become invisible. So, it really will not matter what color He assigned us to begin with. We will be indistinguishable from the air (our egos will cease to exist, and with them our personalities too).
And that is the beautiful Truth I see in the foundation gemstone metaphor of the New Jerusalem: we do not all have to be alike.
You and I can choose to be like John. Others can choose to be like Peter, or Paul, or James and so on. And it is altogether beautiful.
