these schemes try to replicate the default Adwaita color palette as seen in GNOME Console, GNOME Terminal etc.
for tilix place these in ~/.local/share/tilix/schemes
for blackbox place these in ~/.local/share/blackbox/schemes
save this as Adwaita.json
{
"name": "Adwaita",
"comment": "Adwaita color theme",
"foreground-color": "#000000",
"background-color": "#ffffff",
"use-theme-colors": true,
"palette": [
"#241F31",
"#C01C28",
"#2EC27E",
"#F5C211",
"#1E78E4",
"#9841BB",
"#0AB9DC",
"#C0BFBC",
"#5E5C64",
"#ED333B",
"#57E389",
"#F8E45C",
"#51A1FF",
"#C061CB",
"#4FD2FD",
"#F6F5F4"
]
}
save this as Adwaita Dark.json
