I want to block one page with robots.txt

I want to block one page with robots.txt -Specifically the page blue-widgets

Question:
If I code the file like this, would I also be blocking other pages in the shop or products directory?

In other words, would I also be blocking red-widgets because they are in the same directory …. /shop/products/red-widgets

User-agent: *
Disallow: /shop/products/blue-widgets

Thanks for any help,
Jimmy
