+## Important

+This is a dart implementation of [colors.js](https://github.com/Marak/colors.js). After recent events about [Marka](https://github.com/Marak/), I would like you all to donate to me if you want me to keep maintaing this library. Open Source is a place for all and if you want to keep using libraries like this for free, seriously consider donating to open source developer.
