>>> Should I add something to it???

There is a color chart on here somewhere. Let me see if I can find it for you.

I found a couple of things, but none of them say how to get a hot pink color. Here is what I found in case it will help you in the future.

Hope this helps!

I am going to bump this since I have a hot pink fondant polka dot cake coming up and I need an answer to this too. Although... I just need to know what colors to use no matter what they are.

There is a sweet 16 cake in my photos (it is a really bad picture that I am trying to replace) with hot pink on the center tier. If that is the shade you want then all I used was the wilton rose pink. It did not take much to get it that bright. I hope this helps>

I agree with BeeBoos - rose pink makes a petty intense bright pink color. I don't know how to put the "neon" element into the color but it is a nice bright color on its own. Americolor Electric Pink is better, so you may want to order some to have on hand for the next project
