Perspective custom property type inferring

[PGriffith]

At some point, we're planning to add the ability for you to define your own 'schema' for custom properties and view parameters; until then, your workaround is probably the best option.

Perspective view custom property for color

I think the color treatment is dictated by the property ‘schema’, which is the underlying meta-layer that attempts to marshal properties into the right shape. We’ve got a somewhat theoretical feature ticket planned that will expose some way to provide schemas to custom properties on a view - which would allow you (as the view designer) to “restrict” the input and output types.
