When did the world become colorful?

So a few years ago, my little sister and I were watching a tv show set a few years back where the characters were watching an old b & w movie. My sister turns to me and says "Sissy, when did the world become colorful?" I asked her what she meant and she replied "When did it stop being black and white like that? Who colored it?"

That is the cutest quote I have ever heard, to this day.

I don't remember what reminded me of that, but I kept replaying that part of my past in my head today. I am always fascinated by the things that kids say and the way their mind works. But this, this really stumped me. I mean, sure, the answer is obvious in literal sense. "Danielle, the world's always been colorful, the tv set could only show black and white at first." However, I can't help but think there is another meaning to this question. Today, I just cleaned and chilled here, so I had a lot of time to think about it. Thing is, out of all the branches of thought that sprouted off this question; the hours (literally) that I've spent thinking about the possible answers; I came up with only one that would work.

"Sissy, when did the world become colorful?"

"When we found hope."

Side Notes:

Just to clear things up, the blog entitled "sometimes life is like..." is just a blog. No. I did not get turned down by a gay guy. No, I did not fall in love with anyone. But I was having a bad day and I had the same feelings that a girl who got turned down in that way might have. If that makes sense.

By the way, who is "Yours Truly"? It's really bothering me that you won't tell anyone who you are.
