Dithering is a technique used in digital art to create the illusion of a wider range of colors using a limited number of colors. Dithering icons can be created in Photoshop using the following steps:
1. Open the image you want to dither in Photoshop.
2. Go to Image > Mode > Indexed Color.
3. In the Indexed Color dialog box, select the number of colors you want to use in the dithered image. For a basic dithered effect, a number between 8 and 16 is sufficient, but for a more complex effect, you can choose a higher number of colors.
4. Click OK to apply the dithering effect.
