is there any way to get colored notation without the musescore application (or alternatives if not?)

I have difficulty with reading sheet music as my brain has trouble recognizing where on the staff a note is and when the note moves (I have similar problems when reading too). this is my only issue, everything else about sheet music makes sense to me, I just can't play with it because I can't tell the pitches or memorize them for the life of me. I figured colored notation would really help, as it gives me a different way of processing and recognizing the notes, but I can't download musescore's application as my computer is out of date and I can't afford to update it with the risks it poses to my files and other things. I really want to play music I enjoy, but I can't, and I was wondering if there's ANY way to get colored notes on musescore, and if not, other websites that would offer that.
