-I'll tell you what, if you trade the colors you can see for this white light, which is so much better, I bet you'll love every day to the max of your capacity.
-But I don't want to give up my colors!
-This light's awesome!
-No!
-Don't you trust me? Have I EVER steered you wrong? I know you don't know me as well as you'd like to, but really, if you trust me in this you'll see I'm really all for you.
-I just don't want to lose what I have gained.
-You used to see in greyscale and thought that was great. Then you got super excited when I showed you matte blue. And then you were elated with Red, then Yellow. Three shades of Green made your heart burn for life. All this, and more to come, but honestly, you walked with black and white and were satisfied - what have you to lose? The things you gain are currency - experience to buy new experience. Upgrades for enhancement. I won't convince you of anything, or make you do anything. You've dreamt of white light and you loved it.
-...
-Later, then. Did you want anything else?
-...May I see a new color?
-Sure! Which would you like?
