I'll take that as purple~My fave number is 7 and my fave color is any purple shade
Purple: Being the combination of red and blue, you're a mixture of strong emotions and thinking. You don't even know when you'd start to get quiet to think or suddenly blurting out something that you didn't think twice about. Being the color of royalty, you can be very independent (actions) or very dependent (choices) depending on the circumstance that you're facing.
7: Number that reminds me of childhood, wealth, and luck. You can be childish at times, but you also understand that you'd have to be independent as you grow, just like a prime number. You're satisfied with life but hopes for luck to be by your side at all times... (That's me, to be honest XD)
Conclusion: You have both passion and knowledge and you thrive for it. Being strong with both sources, one can take dominance at some point and vice versa. You could be childish emotionally but is very mature knowledgeably. You can waver easily over choices yet very determined over actions. Like every human in the world, you don't want much but hope that life will get better.
P.S. There might be some inaccuracies because this is what I think of you based off of your favorites sorry XD
