Can I use a sdcard for holding led color values to get around SRAM limitations?

I'm looking to duplicate an old YouTube video "line piece" that's a comedy bit. So I'm copying the same layout that happens in there. I'd like to put other things on it eventually so im hoping to get a code in place where I can hopefully use a led matrix program that spits out the frames and then I can put that into the spot where the Tetris frames are. Hopefully I described that right
