ESB knee armor and shoulders paint question

I was about to start painting my knee and shoulder armor ESB style, when I noticed that the left shoulder armor seems to be a brighter yellow than the righ side. The right side has more of an orange tone to it, matching the knees. Would you guys agree?
are there any real good close up pics of those armor pieces used in the movie? i can't seem to find any. Any help?

I have watched ESB twice this week and I was looking at the same thing. On my 55 inch tv with the movie being broadcast in HD the right shoulder is clearly darker and almost looks orange. It looks a little darker than the knees. I was even planning on touching my shoulder up with a little more orange mist. ;)
