Seriously? Not only you want $20 for a color, it’s not even for all mythics present and future. It’s just a color. They’re testing how little they can give you. Soon it’s gonna be “blue Winston glasses for $39.99”.
Is that fr the price of the ‘aspects’? 
Nothing new, they know players love the black and gold colour scheme, it is not hard to change a graphic to that colour so easy money on their side
“I never asked for this.”
You mean $25 when you fully unlocked a mythic already?
