RampReport
The quality of a colormap table, measured (field-presentation §FVC-9).
In the namespace utility::color. Declared in src/libs/libutil/utility/color/RampCheck.hpp.
Detailed description
`neighborDeltaE` holds the smallest CIE76 ΔE between entries 1/16 of the table apart: in the plain view, then under protan, deutan and tritan simulation at full severity. A ramp whose neighbors fall together under a simulation hides a change of value from that reader.
