Selecione um elemento HTML e troque suas cores usando esta paleta de cores do material design
Material Design Palette is an easy-to-use extension where you select a HTML element or type in a CSS/jQuery selector and you can change, in real time, its text, background and border color using its embedded material design colors (palette).
After some changes, you can just copy the generated CSS code and save on your HTML page.
It is intended to make HTML elements color changing fast and easy.
