    # Color palette:
    #
    # black = [       give each color a distinctive name
    #   "#000000",    hexadecimal color used in GVim/MacVim or "NONE"
    #   0,            integer between 0 and 255 used by terminals supporting 256 colors
    #                 or "NONE"
    #   "black"       color name used by less capable color terminals, can be "darkred",
    #                 "red", "darkgreen", "green", "darkyellow", "yellow", "darkblue",
    #                 "blue", "darkmagenta", "magenta", "black", "darkgrey", "grey",
    #                 "white", or "NONE"
    # ]
    #
    # If your colors are defined correctly, the resulting colorscheme is
    # guaranteed to work in GVim (Windows/Linux), MacVim (MacOS), and any
    # properly set up terminal emulator.

    # Background
    bg = ["#ffffff", 231, "white"]

    # Darker background shades
    bgd_1 = ["#eeeeee", 255, "white"]
    bgd_2 = ["#e4e4e4", 254, "white"]
    bgd_3 = ["#dadada", 253, "grey"]
    bgd_4 = ["#949494", 246, "gray"]

    # Foreground
    fg = ["#121212", 233, "black"]

    # Lighter background shades
    fgl_1 = ["#303030", 236, "black"]
    fgl_2 = ["#4e4e4e", 239, "darkgrey"]

    # Accents
    purple = ["#af5fd7", 134, "darkmagenta"]
    orange = ["#d75f5f", 203, "red"]
    grey = ["#6c6c6c", 242, "darkgray"]
    green = ["#008700", 28, "darkgreen"]
    red = ["#af0000", 124, "darkred"]
    yellow = ["#d75f00", 166, "darkyellow"]

    # Highlights:
    #
    # You can define highlight groups like this:
    #
    #   [ "Normal",       name of the highlight group
    #     white,          the color used for background color, or use "NONE", "fg" or "bg"
    #     darkgray,       the color used for foreground color, or use "NONE", "fg" or "bg"
    #     "NONE"          style, can be "bold", "underline", "reverse", "italic",
    #                     "standout", "NONE" or "undercurl"
    #   ]
    #
    # The sample above tells Vim to render normal text in dark gray against
    # a white background, without any other styling.
    #
    # Or you can link an highlight group to another. Here, "Title" will inherit
    # its style from "Normal":
    #
    #   [ "Title", "Normal" ]
    #
    # In GUI Vim, there is an additional color for the undercurl used to
    # highlight spelling mistakes:
    #
    #   [ "SpellBad",     name of the highlight group
    #     "NONE",         the color used for background color, or use "NONE", "fg" or "bg"
    #     red,            the color used for foreground color, or use "NONE", "fg" or "bg"
    #     "undercurl",    style
    #     red             color used for the undercurl
    #   ]
    #
    # The sample above tells Vim to render badly spelled words in red against
    # the current background, with a red undercurl.
