Material Design is Google’s design language and comes with its own colour palette. The colour palette consists of 256 primary and accent colours.The problem? Making the colours usable in your designs. Luckily, if you are using Stylus, I have compiled them into Stylus variables, so you can reuse them throughout your stylesheet.
