The first allows you to search for pictures featuring a particular colour. Simply perform a search as normal, and then choose a colour from the dropdown colours menu:

For example, if you do a search for tulips, you can narrow it down to display just yellow ones, or just red ones. In fact, you can even combine two colours by fiddling the URL of the search yourself. Colour search adds a parameter to the URL of the form: imgcolor=red. By adding a comma and then another colour, you can search for a combination – for example, pictures of tulips with yellow and blue in them: imgcolor=yellow,blue!

The second update is Google Similar Images. This lets you see similar images to a particular image in your search results. So perhaps you search for London:

And you see a picture of Tower Bridge that you like. If you click the ‘similar images’ link beneath it, you’ll get back a page of… similar images!
