Material UI Colors is an online tool for creating colour palettes based on Google’s recent Material Design rollout.
This website is made for developers and designers who want quick access to the colour codes provided by Google for Material Design. You can click on the colour box and respective colour code will be automatically copied to your clipboard.
You can change the colour format you want to use by changing the selection in right side of the header. You can switch between HEX, #HEX, RGB and RGBA.
