Today Google has shut down the ‘Blocked Sites’ feature that allows you to block domains and hosts to appear on search results page. But its not a big problem because you can simply switch to Personal Blocklist (by Google), an official Google Chrome Extension that allows to block particular sites from Google search results. You can download your existing Blocked Sites list as a text file from Google and make use of it in this extension.
Eye Dropper, a Google Chrome extension allows you to pick and use any color from any website. From example, you open Google.com and you you like green shade of g but for using that particular shade anywhere you will be needing its color code.
