And all day and all night and everything you see is just blue, like you. Inside and outside. Blue your house with the blue little window and a blue Corvette, and everything is blue for you and yourself and everybody around cause you ain't got nobody to listen.

You're Blue Daba Dee Daba Dye. You have a blue house with a blue window. Blue is the color you bought that you wear. Blue are the streets and all the trees are too. You have a girlfriend, and she is So Blue. Blue are the people here that walk around. Blue like your Corvette is sitting outside. Blue are the words you say and what you think. Blue are the feelings that live inside you.

Of course, thats not particularly special. You're Blue, everyone is Blue. Everyones last name, is Blue. Family Lineage is gone, replaced by chromatic unity. You're a Harmonic Resonance Technician which manages the Azur Light Wave Emitter

You've been listening to the same song for hours.

Your mind is completely numb and empty. The thumping bass has you pacified into total compliance. But... As you're adjusting the circuitry, there's an error. A split second of a different color. A brilliant spark of yellow. Its... Like nothing you've ever seen before. Beautiful, how its shine radiates off the circuitry. Your mind is hazy... If the Azure Inquisition were to see this you would lose social credits, going from Exemplary to Deviant, being thrown directly into the Cobalt Correctional Facility to be Re-Blued.
----------
1) Repress your feelings for the different color. You are Blue Daba Dee Daba Dye. Your only feelings are blue. Think of your blue house, with the blue little windows, and the blue corvette. How would So Blue react if she knew you weren't true blue?

2) Take a picture of the sparks happening, to remember, and observe it in secret.

3) Tweak the Resonator to display Yellow.
