Regarding this same issue - on-hover icons - in Protean, we see in the Settings for "Body" and "Header": "On-hover icons color". However, the "Main Menu" setting does not offer this particular field. Hmm. I guessed the icon color was automatically synced with the menu text.

Neither icon setting causes the main menu icons to change color in the hover state, for the Body and Header settings. The font, right under the large icons, does indeed change color in this main, floating block menu.

What am I missing? Perhaps I can add additional css to the Custom Styles? Or to the Main Menu itself in the Navigation module, for each icon?

I need the hover state for the icons to change their color with the text in this home-page main menu. To: rgba(51, 102, 255, 1)

Thank you for guiding me, if you are able!
