lol haha yeah it's from your first group buy so long ago, the man formerly known as Lysol.
Oh Ki Bored, just be warned. Filco is actually more like beige than white, so in general it's a bit hard to do color match on keycaps. You noticed in my picture it's not exact match, though imsto keycaps are actually light grey so it's not too bad.
If you want pure white keyboard you might have to look into Ducky or Rosewill.
As for keycap with blue lettering. If you don't mind ABS here is another option:
http://www.wasdkeyboards.com/index.php/galleryWASD Keyboards recently acquired the technology to print any color on your keycaps now, so you can really design the color and font you want.
My dream set will be white keycap with sky blue front printing.
