A vector graphic is an image built from lines, curves, and shapes using a vector-editing software program such as Adobe Illustrator. Because of their construction, they can be resized up or downwithout any loss of quality, which makes them convenient and popular for web and mobile use, and for large-sized printed, works such as banners.

- Make sure that you are working in RGB and not in CYMK or another color space. To check, go to Image > Mode and ensure that it's set to RGB.
- Check what color profile Photoshop is using. It should be using sRGB IEC61966-2.1, which is considered a standard for most PC monitors. The easiest way to check is to go to Edit > Color Settings. If it's set to the "North America General Purpose 2" or "North America Web/Internet," it should work fine.
