This exposes something a bit funky about Safari (both on Mac and iOS). Apparently, it does not support color fonts. If you do your typing in Safari, you’re words will appear in black and white.

I’d love to see the creator of this site add more logo letters to the font. There are two capital M’s (Monster and McDonalds), but only one capital A.
