christmas is red & green, halloween is orange & black... are there any others?

technically the national holiday of each country usually has the country flag colors , right? :D

I don't know if Easter has any specific colors. it's usually just a wild mix because spring time is a wild mix.
maybe yellow and green for that one?

also, I think Halloween is purple too.

and Pfingsten in Germany is pink imo (because of the roses lol)

easter is "pastel" in general imo, but not any specific colors of pastel

american independence day is of course red/white/blue, but yeah i assume like kleeder says any country's national holiday will probably be their flag colors

new year's i feel is like white/gold or so? maybe that's just the vibe?

valentimes is red/white (and a little bit of pink too)
