Painting cookies HELP LOL

So I’m trying to paint these sugar cookies I made, but I ruined half the batch by using gel food coloring. I covered the sugar cookies in white chocolate and thought I’d be able to paint the chocolate with the gel food coloring. Maybe I shouldn’t have put the chocolate on there? I have 6 more cookies, how can I fix these? His party is tomorrow! They look like Pokémon that have gotten into some of that blue candy on breaking bad 😂😂😂😭😭😭😭😭

Do I need to just make a whole new batch? What’s the best way to color/paint cookies? I need them to be vegetarian friendly due to some guests having allergies.
