Solid Color
A solid color hero is a cool, minimalist option that works best on informational sites or on the internal pages of sites rather than the homepage. If a solid hero is placed on the homepage, it would probably be best accompanied with some sort of splash image, slider or module that can still grab visitor attention, perhaps with a call-to-action or cool row separator placed at the bottom.
This solid color hero example takes up about 1/2 of the screen height and is using the "stamp" row separator.
Gradient
A gradient hero is a cool, minimalist option that works best on informational sites or on the internal pages of sites rather than the homepage. The gradient can be set to linear or radial. If a solid hero is placed on the homepage, it would probably be best accompanied with some sort of splash image, slider or module that can still grab visitor attention, perhaps with a call-to-action or cool row separator placed at the bottom.
This hero example takes up about 1/2 of the screen height and displays a gradient background set to "radial".
