Why FLRK as Flare, when it can be KLRF as Colorful?

Edit: Seriously, silent K? I mean, I saw RFLK, but...the "tion" at the end seemed a bit much (colorful bothered me, too)

Edit 2: Yeah, I probably won't fill that last spot. I leave and come back to 4 pages already. I'll probably just read this one. ><
