Image modes for Canvas paint objects In Canvas, image modes define the color model and the number of colors that can be used in images. When you create a new paint object in Canvas, you select an image mode: Black & White, Gray- scale, RGB Color, CMYK Color, or LAB Color. When you select a paint object, Canvas displays the image mode in the information area at the right end of the Status bar. How image modes affect image filters Filters produce different results depending on the image mode. When you paint, the opacity setting of a brush acts differently on images in different modes. For the most predictable results with filters and paint tools, use RGB Color mode. How Canvas assigns image modes When you import an image from another source either by opening, placing or pasting an image file, Canvas assigns an image mode based on the number of colors and the color model used in the image. The following table shows the image modes that Canvas assigns when you import images in some common image formats.
