Please don't change the font color of any literary piece you write. Sometimes, this might inconvenience a reader. For example, I'll be blunt. Pale pink text on pale background actually (literally) hurt my eyes at first glance, and in attempting to read it, I had to highlight the text. So... yeah. Not to be mean or anything, but please don't mess with font colors.
As for the poem itself, it's a pretty standard haiku. The syllable count's fine, and it was a cute little message. My only word of advice here (besides don't change the font color) is that you'll want to remember that haiku is all about saying a lot in a little space. You only get a few words, so you'll want to evoke as much emotion in a reader as possible. (Traditional haiku typically focuses on describing a particular image in detail to poke the reader's senses into synching with their imaginations, if that makes sense.)
Likewise for this. I feel like you could have said a lot more (maybe described what it felt like to be in love), but you stuck with just the order to love and cherish our partners. As a result, it didn't quite engage me as much because I just didn't feel too connected to what you were saying. Or, put even more simply, it felt like the speaker was removed from the emotion – like they were observing someone instead of actually being the one in love.
I'm not sure if I'm making sense here because it's pretty late, but I guess what I'm saying is I'll agree that it's a cute haiku with a pretty important message. It just needs a bit more emotional spark.
