If we spend time setting up a website to use color values from CMS collections it would be nice to have the same option for Hover States. Doesn't make sense why this does't exist yet. I want to set up my sites to be as easy to use as possible and if I can only use this option for the initial color value on buttons lets say it makes my site look pretty static. But to be able to pull an Accent color lets say as the hover background color for a button as just one example would be so useful.
I hope you guys feel the same and vote this up :)
