yes there is a color option on the product page:
there is green (GWA), red (EWA) and soon Super Red (SRWA). I currently have 1 green GWA and 4 red EWA in stock, but I'm re-stocking as we speak.
You select the color on the product page before adding the product to cart , no need to mention it in the special comments.
in this youtube video you can see the green (GWA) http://www.youtube.com/watch?v=HUh9FV0-DX4
I also want to add blue to the color list but it's gonna cost aprox .20-30 $ extra because blue bargraph LED's are really hard to find and they need to be custom made,
so I'm still researching on that idea.
I'm attaching a photo with red EWA and super red SRWA so you can see the difference. (left EWA right SRWA, you can see that super red is much brighter.)
