Research direction

Start by locating the addScalarQuantity entry point and tracing how NaN values currently map to zero. Add an optional glm::vec3 color while preserving the current behavior when it is empty, then check the existing tests or examples for scalar quantity rendering and verify both paths.

Written by the indexing model from the issue text.

Description

While debugging scalar quantities, I find myself often overlooking NaN values, because as it stands, they (seem to) get mapped to zero. It'd be nice if we could specify the color that NaN values should map to, so they're easier to distinguish. perhaps as an extra optional<glm::vec3> argument (if empty, default to current behaviour) argument would help.
