Help needed with toilet water connection

Look in the lawn sprinkler/irrigation area or a hardware store for "funny" pipe connectors or flexible pipe. I used a flexible sprinkler pipe and it fit perfectly on the toilet and the RV piping as it came from the store. No other fittings needed, it is blue plastic and very bendy but it is not a color match for the rest of the toilet decor.
Oh well, my trailer is 25+ years old and decor is not the priority.
