Black&White stack to RGB

I have a problem with the stack below. This should be a stack of fluorescent images in RFP but I don’t understand why it’s in b/w. Is there a tool in image to visualize the proper RFP channel in the stack?
Thanks a lot for the help!

Hi Tommaso,

If you want visualise it in red you can go to Image > Lookup Tables > Red and it will apply a red lookup table to your data. However, you might be interested in knowing that the camera picking up your image doesn’t actually see it in red and in general, it’s better to visualise it in grayscale. Here is a good post about this from @dnmason’s blog,

There are nice explanations about lookup tables in @petebankhead’s ImageJ book here if you want to read more.
