I haven't used the texture nodes much but was experimenting with them today. From everything I have tried, the voronoi node always ends up kind of dark. I like the look of it, but the only thing that comes close in shapes while giving me the brightness I want is the Musgrave node. And it's still not really there. Can anyone help point me in the right direction? My node setups are below for each as well as a low sample Suzanne to help show what I'm talking about. The Musgrave gives much brighter color in comparison. Thanks in advance.enter image description here

    $\begingroup$ Be warned, the reason it appears brighter is the musgrave texture can return values > 1. In your setup this sort of turns the diffuse node into an emission node, as it will then reflect more light than it receives (which is not very physically accurate). $\endgroup$ – gandalf3 Dec 14 '15 at 6:52

I would personally use the ColorRamp node. It permits not only to color but also to adjust the brightness of the result. This can help you: When can a Color Ramp be used to create a gradiant in a Cycles shader?
