About the green and blue... I know some people that think like your
mom, but I just don't see why blue and green are supposed to not going
together,


OK, imagine a green car with a blue interior [try and buy
one - I read the factory won't take an order for a green &
blue car].

they are everywhere in nature and they feel fine there.


The only thing really blue in nature is the sky. There are
[I imagine] a few deep blue flowers but I only know of
a small blue lily.

If you look at the color sensitivity of the eye we are least
sensitive to the blues, with a big hole in the cyan section
of the spectrum: the green receptors peter out before cyan and
the blue receptors haven't yet started picking up signal.

Interestingly, the color completely lacking in nature is cyan.
We can not discern subtle shades of cyan: all cyans look
like turquoise/swimming pool paint.

Where the red and green receptors overlap is yellow, and
we can see a zillion shades of yellow, green-yellow and
orange - and brown, brown being a desaturated low-value
yellow. Green leaves, yellow flowers, most food on the
hoof is brown and hides in the forest/grass among other
brown/yellow/green grasses, forest floor cover. Evolution
makes the yellows colors of great interest. Wasps are
colored yellow/black because it stands out.
