Are they trolling us with colored letters? > I’m actually not 100% sure why this happens It's called sub-pixel rendering or sub-pixel anti-aliasing[1]. Most LCD displays have RGB[2][3] subpixel layouts. Sub-pixel AA takes advantage of this to increase the horizontal resolution of a raster framebuffer by a factor of 3, at the cost of this colour ringing on high-contrast edges such as text—especially on lower-resolution displays. Windows' implementation is called ClearType[4]. It is increasingly less useful as pixel densities increase.
