Hi Richard,

Thanks for your interest, I will illustrate it, probably most clear:
 __________ 
|          |   piece of paper:
|          |
|          |
|          |
|          |
|          |
|__________|

Draw with light-red chalk a line on the paper, under that one
a line with light-blue chalk, under that another red one, total
of 3 red (#), 2 blue (|)
 __________ 
|          |   piece of paper
|    #     |   with chalk lines:
|    |     |
|    #     |
|    |     |
|    #     |
|__________|

Hung this paper on a virtical wall, at about 2 meter high.
I had a broken binoculars, and some prisms from that laying around,
took one (they are (indeed) with 45 and 90 degrees angles), and
stepped some 3 meters away from the paper.

Top-view:
 ______________
[______________] wall
      ^^^ paper







        X me

Then i looked through the prism in a way that it refracts (instead
of mirrors): 
                o
            o  
     |\ o         looking through prism
     o   \  
   o |      \
 o   |_________\
X    

Then i tried to find the paper in the sight, and for that the prism
needs to be turned away from the direct line-of-sight, i turned it
to the left:
 ______________
[______________] wall
      ^^^ paper




     _
     V prism

        X me

I then observed the following:
 __________
|          |   piece of paper
|    #     |   with chalk lines 
|     |    |   as observed through
|    #     |   the prism
|     |    |
|    #     |
|__________|

This ends the experiment i did, although i repeated it later with
the same results for oil-chalk- and pencil-lines on the same paper.

Then, i drew a diagram showing the light's path's:
light from the red line: #, light from the blue line: | (line refers
to the chalk-lines on the paper):

             #  |  
             #  |
             #  |   bending light from chalk-lines in prism
             #  |   for red-line bends most (topview)
             #  | p
             #  p|.p
             #p...|.p
            p. #...|.p
	  p.p.p.p#p.|.p
                    # |
                       #| 
                          X
                            |#
                              | #
This is the bending where the light from the red-chalk line is bend
more, this results in visually seeing:

             #  |
      |      #  |
        |    #  |   Visual illusion (topview)
  #       |  #  |
     #      |#  | p
        #    #| p|.p
           # #p.|.|.p
            p.##..||.p
	  p.p.p.p#p.|.p
                    # |
                       #| 
                          X
                            |#
                              | #

I concluded that this is what i saw,
 __________
|          |
|    #     |
|     |    |
|    #     |
|     |    |
|    #     |
|__________|

                                     and therefore concluded that
the light of the red-chalk line was refrated more than the light
of the blue-chalk line.

If i made any mistake, do not hesitate to point it out to me!
