If you have full-value red and blue (and not 'darkened' colors with
additional black, white, or other color component such as green), you
can just convert the color image to a RGB stack and use any of a
number of plugins or built-in tools to check the intensities.  Things
will get more complicated if the red/blue LUT you have in the images
is not full-value.
