Color representation is more determined by panel type. Usually IPS panels have better color representation an that is even more important if the output of the content is going to be actually printed as photoes or posters and such, like book covers for example. I would focus on the following than refresh rate (Hz).
Another factor is color depth (8-bit versus 10-bit). Monitor with higher color depth (this varies based on brand and model) show higher number of color shades. In other words they show more color, more detailed fading of color if you like; that is, the fading is more gradient.
Also important is color space. Color depth as I said is the number of gradients between white and red, for example. The color space determines how red is the most red spot/pixels. For photo editing a monitor that supports all or a larger portion of Adobe RGB color space (aRGB) is better and for video editing a minotir that supports DCI-P3.
I would also add that local dimming helps with seeing better light and dark spots in photos. It works by lighting the lighter spots of the photo/picture more and not lighting the darker spots. Contrast ratio also helps with more realistic picture. If a monitor has a 10,000:1 contrast ratio it means the the lightest pixel is 10,000 times lighter than the darkest one.
TL;DR
- IPS panel
- Higher color depth (10-bit way better than 8-bit, 60 times more colors)
- Adobe RGB (for photo editing) and DCI-P3 (for video editing)
- Higher contrast ratio / Having local dimming
