This hasn't been about enjoying colours. I'd rather be dressed in white than purple or many other different colours, it costs less to be dressed in white and there is more money for the poor in that way.
Magenta may want to use purple to make it appear that she's a Christian, God wants me to use white.
Revelation 18:
16 and cry out: "'Woe! Woe to you, great city, dressed in fine linen, purple and scarlet, and glittering with gold, precious stones and pearls!
Revelation 3:
5 The one who is victorious will, like them, be dressed in white. I will never blot out the name of that person from the book of life, but will acknowledge that name before my Father and his angels.
