How do you convert a grayscale tiff to be white on a colored background?

[nickn25270132]

So you know how you can bring in a grayscale tiff into illustrator and change the color to what ever color you want? This works great if the background is white but what if I wanted the tiff to be white on a colored background? Think a painted grayscale circle for a snowman on a blue background. Any ideas?

do you want to colorize the grayscale image or place the grayscale image to colored BG? If last, just delete the background in Photoshop and save the file with transparency saved (turn On this option in Save Tiff Options dialogue).

AI will read the transparency and your gray image will show the colored background.

Hi.

Maybe this trick will help you: 1 Bit Bitmap

Use the TIFF as an opacity mask. Think of a stack of thee objects, from bottom to top: Background colour (rectangle filled with a colour), image colour, TIFF. Select the TIFF and the foregound colour then go to Make Opacity Mask in the Transparency panel. You might need to invert the mask.

Good evening, Scott.

Nice to see that you have not passed away already (though the images may indicate something different).

Hope you are fine.
