My empeg came with an non-AR blue. I wanted a Green screen to try and match my car display and those kind and wonderful empeg people shipped out an AR one for free. I found that the brightness was greater on the Blue than the Green and the Green was was slightly easier to read in sunlight. It was mounted high up in a Golf dash. I have now changed my empeg into my Escort where it is mounted quite low and at a slight angle. I recently had to contact those those kind and wonderful people at empeg about my control knob and asked when the screens would be available on the site. Within 2 days I got a new control knob and an Amber display. I have found that this is not as bright as the Green screen and is difficult to read in sunlight. Not much more than the Green, actually. But, when it's sunny I tend to be wearing sunglasses and this doesn't help. I find if I peer under the glasses then I can make out the display.
I am seriously considering going back to the Blue for several reasons. First, the Amber didn't match my display as I'd hoped. Second, I don't really have any instrumentation close enough for it to make a difference and it is all a kind of off-white anyway. Third, I was recently trying all my screens in situ for a photo session to put on the web and found that I actually quite liked the Blue. Finally, my Escort is Blue.
So, after all that, what you really need is a comparison off someone who has had an AR and a non-AR of the same colour.
