Ok so I bought a durex condom pleasure pack and now I cant tell which condom is which?

I threw away the box so I cant just refer to the box. Ummm there were 4 different types. One type is orange, the other gold, the other light blue/purple, and the other is grey. Which one is which? I know there is one that is supposed to make you last longer in bed by numbing you up. I wanna throw that one away lol or give it to my roomie or something. But I need to know which one it is.
