What about a ColorField that implements a color scale

[martinweismann]

that is a ColorField that assigns a color to a scalar value as is often used when visualizing simulation results:

@asartorellihxgn : please add/change use case for you

Color fields can often be used for display information from scalar simulation results fields on 3d printed geometry. With the current implementation of color field, if one were coming from a simulation tool then they would be locked into a particular color map. This could present a few issue when physically printing parts:

1. If one were to export a part containing a color field generated from a simulation field where peak stress is say 1MPa and this corresponds to red on the color map, and then later exports another part that will be used for comparison where peak stress is 2MPa and this also corresponds to red on it's color map. Then one is not able to readily discern the difference between the two. By storing the data of the underlying scalar fields and converting to a color field at a later time, they could use a matching color map where 2MPa is red and 1 MPa is green for example.
2. There exist a large variety of color maps to convert from scalar fields to color fields often products from even the same company may use a different color map. It could be useful to end consumers to be able to use a matching color map regardless of where the original data is coming from.
