Hi there.

I am a 65 year old man, and I think about a lot of things, and I am here to discuss matters.

Hello!

I'm pulling Welcome Wagon duty today.

Please enjoy this package of hamburger buns.

Cool...what matters exactly? Whatcha thinkin about?
OK, here is something, this world is full of perfect color, like the blue sky, and the green trees. My question is why isn’t the sky green, and the grass blue? And why is fresh water transparent? I have my own thinking on that, but feel free to give me your thoughts.
 
Welcome.

Don't count on much discussion though.

The place generally runs afoul of those who already know everything and want you to know it the same way they do.
I am used to it, it’s like that everywhere.
 
Because the ocean is blue

because of chlorophyll

because its molecules do not absorb light in the "visible range"
Now, think about something else :)
Who chose the colors is what I am getting at. Life on Earth would be unbearable if the sky were green.
