Alpha colors incompatable.

Versions (please complete the following information):

• Win10
• VS Code 1.38.1
• Peacock 3.1.5

Describe the bug When using CSS alpha colors, the auto-contrast for menu & icons does not work.

To Reproduce

"peacock.favoriteColors": [
        {
            "name": "Nord: Auroa Red",
            "value": "#bf616a4d"
        },
        {
            "name": "Nord: Auroa Orange",
            "value": "#d087704d"
        },
        {
            "name": "Nord: Auroa Yellow",
            "value": "#ebcb8b4d"
        },
        {
            "name": "Nord: Auroa Green",
            "value": "#a3be8c4d"
        },
        {
            "name": "Nord: Auroa Purple",
            "value": "#b48ead4d"
        },
etc

Expected behavior The menu & left-icons to be legible

Screenshots You can see the ‘base’ color in the window behind the dark-orange peacock-themed with alpha.

Additional context Kinda low priority. Quickest way is just post instructions how to set the menu foreground colors. A good comprimise is to add optional fields to each theme color:

"peacock.favoriteColors": [
        {
            "name": "Nord: Auroa Red",
            "value": "#bf616a4d",
            "menu": "white",
            "icon": "lemon"
        },

Thanks for your great work.

The light and dark foreground settings can be used to explicitly override the readability choices, though the detection of dark/light background could be off based on the transparency of the color as well.

@tomByrer Peacock works by writing to the workbench.colorCustomizations key in the local .vscode/settings.json file to modify the colors of different elements. After using Peacock to establish the colors, you can easily manually adjust any of them in that file to your liking. In your case, you are probably most concerned with any of the foreground keys and/or activityBarBadge.background.

Interesting. The latest issue on TinyColor relates directly to this https://github.com/bgrins/TinyColor/issues/209
