If you’re like most people, you open color swatches in Photoshop to get a sense of the colors that will be used in your project. But if you’re new to Photoshop, there are a few things you should know before opening color swatches. First, Photoshop doesn’t support transparency so any colors that are shown in the swatch will be completely transparent when the image is displayed onscreen. Second, if you want to see how different colors look together, it’s best to open each color separately and then combine them into a single swatch.
