Adobe Color (formerly Adobe Kuler) is a great website to try out colors and get an idea of how colors look in connection with other colors. Color swatches can be saved as well.
Pixabay is a fun site to look through for stock photos. Stock photos can really jazz up a website but you need to be sure that the images are free for reuse. This site has some great photography and it’s all usable. It also links to Shutterstock photos which are not free.
