user126793: Why is Bitcoin colored everywhere in orange even when the historic late 2000's color was some yellow-ish / gold-ish? In some places e.g. the Bitcoin group at GitHub, it seems to be portrayed showing a less informal black color.
Some additional related doubts, maybe for other independent posts:

Why did Core specifically choose orange for their color?
Why is the large blockers' fork so frequently portrayed in green color?
Why is the Wright fork so frequently portrayed in yellow color?
Why is testnet colored in green and signet colored in pale green (in Core)?

As mentioned by Pieter Wuille in comments:

The current Bitcoin logo was adopted in the reference client's version 0.5.0 in 2011 (but it wasn't until 2014 that it rebranded to the current name Bitcoin Core). The logo was designed by bitcointalk user "bitboy" here: bitcointalk.org/index.php?topic=1631.msg19455#msg19455, and was not intended to be specific for one piece of sofrware.

First logo created by Satoshi had golden color and BC written:

Satoshi updated logo which had similar color but Bitcoin symbol ₿:

Bitboy's logo had orange color:

There is one more color (black) which is used at few places for Bitcoin Core:
