Cocktails for a pride parade

Hello everyone. I Am involved in organising my Citys queer pride parade, and the Afterparty in our students club. For this quite special occasion we thought that it might be a cool idea to offer some themed cocktails on the party. The problem is, I have no Idea what might be fitting and I have never mixed a single cocktail in my life. Thats why I thought, that I might just ask you, if any of you have some ideas for some cocktails (alcoholic or non alcoholic), that might fit the theme of a queer pride parade, that are easy to mix.
