Review of Libra colour and comparison with Libra 2
https://archive.md/rsMub
Key points
1) colors are cool
2) they immediately noticed a color lattice over the screen causing a sort of rainbow effect that goes away once they're concentrating on the text
3) worse contrast and clarity than Libra 2
4) any time there's any color on screen the device resolution seems to take a hit
Of course these are their subjective impressions. YMMV
