placeholder_text doesn't use font_color

[alba4k]

It instead seems to use the default. I'm not saying it should use font_color, as that would be too saturated and probably confusing. Maybe placeholder_color?

maybe not placeholder_color as it's used for feedback too

secondary_color? message_color? no idea

You can color it with pango's markup:

placeholder_text = <span foreground="#aabbcc" style="italic">Input Password...</span>

That still doesnt change the color of stuff like "Authentication failed"

btw I think you need to escape the # with ##

Thanks tho!

I've named the variable placeholder_color, maybe feedback color could be another variable considering the fact that many people probably want different colors for negative feedback vs. reminder.
