When querying the terminal for background colors, an assumption was made

that we'd always have input. We'd block forever with the assumption that

we had data to read, and this wasn't always the case. It'd then require

mashing on keys until the read buffer was filled, if the terminal and

pipes indeed even fed the keyboard input to the process.
We now put stdin in non-blocking mode and read so long as there's data

to read, until we hit a result with a terminator, fill up the buffer, or

time out.
Along with this, we had a bug where we were looking for the wrong

terminator, which contributed to this blocking issue. The correct

terminator is now used.

Reproduced on a system that was blocking on startup and then interfering

with reading stdin. Verified this fixed the issue I was able to

reproduce.
