Ginger was hinted at in the Iridescence album cover

On the album of Iridescence it shows a pregnant lady in thermal vision and there’s a bar on the left with the colors blue, green, yellow, red, white. The stomach of the pregnant lady is red and white..

I believe Ginger is the baby of the Iridescence lady. With how the colors of the bar are the main saturation colors leading into the new white and red aesthetic. It really seems like they may have had an idea of what they were doing after Iridescence. It does seem like Ginger is the true sequel to the Saturation trilogy with the return of the blue paint and jumpsuits too, imo.
