To create a suitable Automator workflow, proceed as follows.ġ. Besides, once you realise the power of Automator and what else it can do, you’ll be tinkering with it for days automating many other daily tasks on your Mac! Building The Workflow Using Automator means that you don’t need to mess about with complicated scripts, and it’s also built right into Mac OS X so it’s by far the easiest option. The renaming options are extensive – it’s possible to add the date and time, insert custom text strings, change the case, make them sequential, and so on. You can use the workflow within Automator or save it as an application that allows you to drag and drop the files you want to rename when needed. Create an Automator WorkflowĪutomator allows you to quickly create custom workflows to rename your files. If enabled, it will show exactly which colors in the input PNG got matched.As you can see, there are no shortage of suitable renaming applications, each with slightly different capabilities and prices. Also, for your convenience, we've added the preview mask option. To get rid of these pixels, you can use the edge smoothing option, which mixes the colors of the old and new pixels, making a smooth transition between colors. Often, pixels of the original color pixels still remain on the border or at the edge of old and new colors. It looks at the lightness parameter (geek note: that's "L" in "HSL") of the original pixels and sets the same lightness for the pixels of the new color. To preserve tints, shadows, and gradients in the output PNG, you can activate the "Preserve Color Shades" option. If the similar color match option is set to a value that's greater than 0%, then not only the indicated color is replaced, but also its shades and tones. All pixels of the selected color are immediately replaced with the new color and you can see the effect in the output preview field.

The color for the replacement can be specified in the options as a color name, color code, or rgb(r,g,b) function, or you can select it directly from the input image by clicking on a color pixel in the input PNG. For example, you can match 10% of possible green colors, which include sea green, jungle green, and forest green.

For example, you can quickly swap red with blue, or yellow with white. This browser-based utility replaces any color in a PNG (Portable Network Graphics) picture with a new color.
