paint.invert and paint.complement on the Fill proxy, the Edit Colors commands, the Blend commands and recolor.apply now recolor the color that colorizes a grayscale or 1-bit image, as one undo step with the other targets. Before, they left it unchanged. Expand Appearance and Object > Expand bake color adjustment effects into that color too. - A colorized image's pixels are not recolored; they stay the gray coverage of its color. A stroke-only pass reaches the image's stroke items and leaves its colorize color unchanged. - A command that would leave a process color on a grayscale image with an alpha channel fails with the existing message and changes nothing. Object > Expand undoes its earlier steps when that happens. - A colorized image counts as a filled object in a blend.
