Hi,
The problem is that the appearance of an 8 bit image is controlled by
the LUT. If the LUT contains gray values from 0 to 255, every
"color" will appear as gray.
There are two possible solutions.
1. change your LUT from gray scale to gray scale with either the 0
or the 255 value set at a color that you like. Then set the
foreground color either to 0 or 255. You can do this by going to
Image>Colors>Edit LUT. Of course, if you do this, you will lose
access to the 0 or 255 value pixels in your original image.
2. Change your image to RGB. Image>type>RGB
