Hi Sharmon,
You could use the Magic Wand to select the white foreground and then fill the selection with red (Edit fill) by changing the Foreground colour in the colour palette.
I'm assuming that your background is all the same grey value, i.e. white and that you want a solid red foreground.
Otherwise, you might be better to make the image greyscale and then use/create a Look Up Table.
Kind regards,
Jacqui

Hi,
I have an image that currently has a black background and red foreground. What I want is a white background with a red foreground for easier viewing in a presentation. I'm wondering if this is something that can be accomplished in ImageJ. I've tried importing an .ims file as a hyperstack using custom coloring (white foreground, black background) and then inverting the image but is there a way to then change the foreground to red?
