Lime green and black could work well, I just think it shouldn't be for Canberra with the Raiders basically owning lime green.
I wouldn't want it as a primary colour, but I'm fine with lime as a secondary or trim. Something like the below (good call with Bing Coolangatta). Canberra United use lime, so to do the Sydney Thunder (which play part-time here and people are pushing for a Canberra relocation). It was originally a Raiders colour, but I think it's evolved to more of a Canberra colour (like Brisbane and maroon).
My preference is probably still the blue, green and yellow like Coolangatta had earlier. It works well for Woodville-West Torrens in the SANFL. Blue and yellow would've been perfect if the Eagles weren't already in. I like green and gold too, but might get pushback from going with the national colours.
