why does everything have to be fucking blue???
I understand your frustration.
But it is not by accident. There's science that stands behind it.
Each colour has its particular meaning and resonates with certain mental-emotional frequencies in your brain. You don't have to be a designer, photographer or clairvoyant to be affected by these different colour qualities, everyone is. But for most people, this works on a deeply unconscious level and has nothing to do with their personal taste. These "colour laws" work in the same way for everyone regardless of their colour preferences.
Now, for an entity that aspires to be the new, widely adopted worldwide currency, there is really not too many colour options to choose from. As a quick experiment, can you imagine the US dollar bill in purple, yellow, pink, baby blue, red...? It doesn't work, does it?
Absolutely ideal colour to represent money, psychologically, energetically speaking, would be a kind of
olive green (see example below). This colour resonates spot on with money. And not because the old dollar used to use it, actually the other way around - dollar used it because the people who were in charge of designing dollar bills knew about this stuff and applied many "tricks" to make dollar bills look as powerful and trustworthy as possible.
I thought about this for a long time and decided not to propose the green option for a few reasons. One is, this particular, olive green would be even less likely to win over the hearts of long term bitcoiners. It's sticky, looks a bit dirty, impure... And if we're going to change this it really needs to get support of the core community. The other reason is that other than being just money, Bitcoin is also a technological phenomenon which makes it strongly resonate with blue. Again, it is no accident that Intel, Dell, HP, IBM and a million other tech companies have tech-blue logos. And then there are also these elements of cleanliness, innovation, simplicity and freedom (blue resonates with these qualities) that resonate with Bitcoin but definitely not with money per se.
Orange is not an outright terrible choice (as red or purple would be) and it even has certain qualities that are beneficial (encourages growth and multiplication), yet it still doesn't stand a chance when confronted by blue or green as described above.
