Message: <blockquote data-quote="typo" data-source="post: 3426591" data-attributes="member: 83808">James and others,If we go back a few years there were frequent arguements about the FL's colour rendition on the forum. Some said it was neutral, others "steely blue", even rather warm, but I, like a few others, saw it as having a yellowish tinge with rather muted reds. I suppose it might have been sample variation, but I guess I've tried at least 20 and any differences appeared very minor to me. The 3 FL transmission profiles for FLs on Allbinos all show a peak in the 560-580nm region and a pronounced if variable tail-off in the red. I've also commented of variation in the colour rendition of ELSV and SLC which others disputed as well. Sample variation could still be at the heart of this, or some other factor like viewing conditions, but it does begin to point to the user as the other variable. We do see differently. It's partly in our genetics, the variation in the physical and physiological make-up of the eye, and the way our brain choose to interpret the signals from the eyes. All I can say is when I see a binocular with a yellowish tinge and muted reds I expect to see a transmission profile exactly as reported by Allbinos. I fully accept that many, possibly the majority, might interpret it entirely differently.David</blockquote>
