Well a new app named Material UI Colors offers a free color generator that follows in-line with Google’s desires. Anyone can use this app to generate colors that match well and work best with Google’s design language.
All colors are given names along with codes for use in HTML/CSS. You can switch between HEX or RGB/RGBa which may also be applied to mobile webapps or Android app design.
The site design is incredibly simple with a deep focus on the color choices. A scrubber bar allows you to shift between levels of saturation from pastels, neutral, or deeper shades. And if you click the “MORE” link beside each shade you’ll find a host of similar colors to choose from.
While not everyone actually uses material design, but those who do will surely enjoy the simplicity of this free online color tool.
