My monochrome icon theme
    I have an unusual icon theme on my computer (which is specifically
    designed for regular computers and not necessarily smaller devices).
    It's almost completely monochrome, grey to be exact, although you
    can select the colour yourself. The reason I want all icons to have
    the same colour, isn't that it looks good, although it does, or that
    it removes distraction, although it does, it's because colourful icon
    themes is bad UX design. I'm more senstive to colour than shape, hence
    the description of subpixel rendering on text looking like someone
    sprinkled glitter all over the text feels apt. This means that removing
    colour from icons remove their most prominent feature, which is good
    in this case because many icons share similar colour making it easier
    to click the wrong icon by mistake because they look similar. Another
    failure of colourful icon themese is that warning colours fail to draw
    your attention, this is why may icon theme only uses colour when it
    needs to draw your attention, when the user has specified a colour to
    mark an object into some user defined category.
