The HP 24 Envy is preset to the Neutral setting under the Color Control menu, and its colors are the same at both 60 and 75hz, as well as when the Custom RGB setting (unlocks the Red, Green and Blue controls) is selected in the Color Control menu. The other HP 25-27 CW/er/es/XW monitors colors changed slightly when set to the Custom RGB mode and when their refresh rate was changed. The 24 Envy also does not suffer from a blue or green tint when viewing the White Saturation Lagom page; the 24 Envy does not need to have its contrast reduced from 80 to 75 to get rid of the blue or green tint to greys.

Another issue shared by a few other 24" 1080p IPS/PLS panels is the presence of <1mm thick vertical black lines which span from top to bottom of the panel when viewing some light colors such as light blue, grey and orange. Despite having gamed (Bloodborne, Destiny & Overwatch) on the 24 Envy for dozens of hours and looking at dozens of screen shots I did not notice the lines until the issue was pointed out to me by Magical Chicken here. Aside from the few test images I look at the 24 Envy only serves as a console gaming and YouTube monitor to me (replaced the 25er with it).
After noticing the vertical lines they can not be unseen, however I do not find them to be problematic for my uses (frequent console gaming), but this does not mean that others will notice or not notice the lines; results may vary.
PC Monitors also noticed the vertical black lines on the following monitors:

It's not neutral and not perfect, but very, very few monitors are, and the 24 Envy's Almost Glossy/Low Haze coating further enhances clarity and color vibrancy since it is free from clarity and vibrancy reducing matte coating grain and sparkle. Aside from the black vertical line issue I think the 24 Envy's reduced color accuracy compared to the 25er/es is worth putting up with in order to gain access to its native 75hz refresh rate and AMD Free-Sync for PC gaming. Console gamers and those who do not game should buy the 25er/es instead since it's both more accurate and cheaper. The HP 25-27XW are also still worth considering since they're only slightly less accurate than the 25er/es, can overclock to 75hz and are cheaper than the HP 24 Envy.
