Christ, there isn't even any color in those things. It's the absence of color, my friend, it is the lack of color that is stunning. Art doesn't fucking need the colors. That's why you are a designer and they are artists. Green is the color of money.
People respond to it.
But green alone is tacky, it's too much, you are beating them over the head. That's a turn off. Has to be more of a tropical, fun, lime color. 90's light fun green. Not IBM blue, for chrise sakes.
