    Use {X} placeholders to apply colors. Available colors are:

    w: white, k: black, g: green, l: blue,
    y: yellow, c: cyan, m: magenta, r: red,
    W: bgwhite, K: bgblack, G: bggreen, L: bgblue,
    Y: bgyellow, C: bgcyan, M: bgmagenta, R: bgred,
    d: dark, b: bold, u: underline, i: italic, x: reset

    Multiple placeholders can be combined in a single {} pair.

    You can also use {#RGB} and {#RRGGBB} to specify hex colors.
    Add a b before the # to make the hex a background color ({b#fa0}).
