I always log in to my TTY. Have you tried setting your colour scheme before login? I have a mega janky setup where I add an OpenRC sysinit service that calls setvtrgb. The first lines of the startup log aren't affected but most of them are. That way I can log in with a colour scheme consistent with that which comes after the login.
I used to have sddm but this time I forgot to install it after a clean reinstall of Arch (btw) so I use tty for a few day and I quite like it, I think I'm going to use tty login from now on
Oh cool, I believe only 4bit colours are possible, you can use this table from Wikipedia and the escape sequence \e[<FG>m replacing<FG> with your chosen foreground colour. Also \e[0m to reset everything.
funny how we use the same font XD
Haha yeah! I noticed that too!
I think I just used regex look aheads and look behinds to insert the colours easily.
Edit: Oh you can change that actual TTY font to a bigger one, if the text is too small too.
