I've seen the use of three-color (trichromatic) graphics in multiple places, and every time it ends up looking *really good*. It's (I think?) typically **black + white + *one* other color**. It has a very clean look, while being more interesting than straight up black and white. Examples of trichromatic graphics: - [[The Bullet Journal Method]] - B&W + Yellow - Some other thing I've used in these notes also used black & white + yellow, I just cannot pull the reference - [Google Chrome explainer comic](https://www.google.com/googlebooks/chrome/small_30.html) - B&W + Blue **** # More ## Source - self
