Love it when vendor leaves out minor detail...

I was looking through Amazon mostly to see if I could get good price on Balliztix Tracer. Specifically I wanted the red LED only model but Amazon isn't providing much details on the 5 mystery Tracer listing they have:
http://www.amazon.com/gp/product/B006YG98RU/
http://www.amazon.com/gp/product/B006YG98EI/
http://www.amazon.com/gp/product/B006YG97KS/
http://www.amazon.com/gp/product/B006YG98NE/
http://www.amazon.com/gp/product/B006YG98I4/

No picture either or I would have gone with red = red, green = green, blue = blue, and black = either red/green or blue/orange

So... all of them are listed as having LED but never mentioned what color. If the seller (Crucial) is wondering why they haven't sold a single one through Amazon, there's the answer.

They may as well throw them in a box of Cracker Jacks for the mystery surprise.

The Ballistix Smart Tracers in your links don't have a red only model. There are only two combinations, the Blue/Orange model or the Red/Green model. I think you'll need to look for Ballistix Tracers, not "Smart" Tracers. Crucial's site is helping in the search either...
