Bad error message for out-of-range color

[fredcallaway]

julia> scatter([Point(1,1)], color=1., colorrange=(2., 3.))
ERROR: MethodError: Cannot `convert` an object of type
  Vector{MakieCore.Automatic} to an object of type
  Union{ColorTypes.RGBA{Float32}, Vector{ColorTypes.RGBA{Float32}}}

Seems like a good situation to add an explicit check and useful error. (As a side note, I've found bad error messages to be a common problem with this package)

Please file as many as you can, this really helps! The only way this gets better is by knocking bad messages out one by one.

This issue should be fixed with #4048

I'm so glad to hear that the maintainers are interested in improving error message—I'll make sure to file reports whenever I encounter bad ones :)
