Step 1: Go to the advanced search option for Google Images
Step 2. Once to the advanced page choose the color you want by selecting it in the options. In this case I am searching for blue even though I have not switched it from red yet in this screenshot.
Step 3: Type in your word and you will then have your topic by color choice. So my coffee search with the color blue provides me all I need!
