This is my attempt to create an accessible color scheme for the terminal emulators I use.

• Place Aquamarine.colorscheme in ~/.local/share/konsole/.
• In Konsole, click the ☰ menu in the top right corner, Edit Current Profile…, then Appearance on the left, and select Aquamarine.

• In Windows Terminal, click ⌄ on the tab bar, and then click Settings.
• Click Open JSON file in the bottom left corner.
• Copy everything from WindowsTerminal.json to the end of the "schemes" block. Remember that blocks in the JSON file must be separated by commas, like this:

"schemes":
    [
        {
            "name": "previous one"
        },
        {
            "name": "Aquamarine"
        }
    ],

• Then you can set Aquamarine in the file itself (look for "colorScheme"), or do it in the GUI for a specific profile or as default.

Put colors.properties into ~/.termux/ and execute termux-reload-settings.

Contrast, mostly. I just took base colors (blue, red, purple, etc.) and adjusted them using ColorShark.

I am color blind, but one scheme will not work for everyone. I have adjusted color pairs that give me trouble (yellow/green, cyan/white, etc.), which should work for some people.

This is one of the colors I changed significantly to get away from white and light gray. Otherwise it should be cyan. Then in Nushell, which I use, you type with that color, so it felt as good a name as any.
