Then you need to get creative 
some options:
For what you need (2 colors, fixed text) the best alternative would be a piece of while plexiglass panel with 2 color red/green leds behind it to light it up and diffuse the light to illuminate a logo printed on transparent laser paper (such as overhead foils are made from) glued to the top of the plexi. It may be a bit hard to get the color even across the sheet, but you may not care or even like the effect. The more complex solution would be to use a color display with the logo displayed as a graphic on the display. This (if you don't need a size larger than 1.4 inches) is the cheapest I see but will likely be poorly documented (although it does have a download button for a library and I know of an Arduino library for these on the net).
If you need bigger it has larger more expensive cousins but interfacing them can be difficult to impossible. I'd try the led/plexiglass/bicolor led method first to see if you can get something acceptable. (despite the "Red" in the description which I think applies to the pcb this appears to be a full color display)
