Fill Tool

Use the Fill tool to replace colors in an image to match your brand colors, improve accessibility for viewers, or change the aesthetic.

Fill an Area with Another Color

1. Click the Fill tool in the Snagit Editor toolbar.
   
   

   Note: If the tool is not visible in the toolbar, click the More dropdown. To customize your toolbar, see Customize the Snagit Toolbar.

2. The settings available for the selected tool appear in the Tool Properties panel. To select the fill color, complete one of the following:
   • Select a fill color from the Quick Styles.
     
   • Click the Fill dropdown and select a color from the preset colors or from the color palette.
     
     If you want the image to match the background on any page or if you want portions of the image to display any content behind the image, select transparency fill (checkerboard pattern).
     
     
   • Click the Fill dropdown and enter a HEX or RGB value into the field. Click the Mode button to switch between HEX and RGB values.
     
   • Click the Eyedropper button and then click to select a color from anywhere on the screen.
     
3. Click to apply the fill color to a location on the Canvas. Fill changes the color of the selected pixel and all other pixels around it with the corresponding color.
   

   Tip: Adjust the tolerance for a better result.

   If Snagit fills too little or too much of an area on the Canvas, press Ctrl+Z (Windows) or Command+Z (Mac) to undo the previous fill and drag the Tolerance slider to adjust the fill amount.

4. When you are finished with the Fill tool, click the Move tool to select, move, edit, or delete objects you added to your image.

Tolerance
Tolerance adjusts the amount of fill in an area based on how similar the surrounding colors are to the selected pixel.
