Tweak @theme_base_color to increase the contrast for better legibility
It appears that tweaking
@theme_base_color, making it brighter (
shade(@theme_base_color, 1.1)) when used with the light theme and darker (
shade(@theme_base_color, 0.67)) when used with the dark variant, further improves the legibility of the terminal by enhancing the contrast.
Attempts to globally change the
@theme_base_color didn't work out.
VteTerminal is a bit special compared to other document and text widgets. eg., it uses monospace fonts.
