Directly producing color values for each node

[nakanangdoods]

Is your feature request related to a problem? Please describe.
Hi! I'm a beginner Python user and I am trying to learn how to use the API for the Kepler Mapper. I do not know if there is an existing way to do this with the current API, but I would like to either: 1) find a way to color nodes directly or 2) extract boolean values for nodes using member data.

Describe the solution you'd like
My idea for this solution would just be to directly input the color value for each node, but afaik, the API will only extract this from the application of a numpy array function on the member data.

Describe alternatives you've considered
Is there a way to implement numpy array functions multiple times (say pass np.all(np.isnan())) for the node_color_function?
