On the left is China Glaze Peachy Keen from the Up & Away collection and on the right is China Glaze V from the X Collection. Peachy Keen is described as "nectar" and V is described as a "coral creme" - already by just the bottle pictures you can see that Peachy Keen is lighter and less orange than V.
This is two coats of each color - in the sun, you can tell that indeed, these two bottles are not the samer. V is much more orange and oddly a little more streaky than Peachy Keen.
Same with the shade picture - Peachy Keen is more vibrant and well, peach. Well I tried! Indoors sometimes, I can't tell what's what, especially the way I have my polishes in acrylic spinner shelving units. (I'll have to take pictures soon.)
