Select Canvas > New Image or middle-drag an empty file texture from Hypershade onto the canvas. The Paint Effects New Texture window opens.
Type a name for the new image in the Image name box or click the folder icon and select an existing texture. By default, the image will be stored in the sourceimages directory
for the current project.
Set the canvas size, if necessary. For textures, you typically use a square canvas (for example, 256 x 256 pixels, or 512
x 512).
Click the Background color box to open the Color Chooser.
Select the background color for the image and click Accept. For information on using the Color Chooser, see the Basics guide.
