We just got some new chips . At first look, I thought they were "the same" chip...on closer inspection (and after cleaning) it looks like the Frontier name is turquoise on one chip, more teal on the other. Do you have these chips? Have you seen the color difference?
(These scans, not mine obviously!, were before the chips were cleaned)

After cleaning (sigh...my photo) the color difference is even more noticeable.
