Terminal text highlight

Hi,

Is there a way to change the terminal text ‘highlight’ behavior for different items displayed on the command line? For example, the Manjaro i3 community edition terminal’s default executable renders (of chmod +x kind) show up as mildly fuzzier, mildly grayer texts compared to the default texts, which is wrecking havoc with my eyesight.

I’m pretty sure I could do it with .Xresources file, but does anyone know which entry addresses executable type entities specifically?

Thank you!
