Colorfy.jl is a package for mapping Julia objects into colors defined by Colors.jl.
The use of this package is centralized in the Colorfier struct.
This type stores the necessary info to convert a list of values into a list of colors.
To extract the mapped colors from the colorfier, use the Colorfy.colors function:
julia> values = rand(5)
5-element Vector{Float64}:

0.48419175677473947

julia> colorfier = Colorfier(values);
julia> Colorfy.colors(colorfier)
5-element Array{RGBA{Float64},1} with eltype ColorTypes.RGBA{Float64}:

RGBA{Float64}(0.267004,0.004874,0.329415,0.5)For convenience, the colorfy function is defined. This function
creates a Colorfier instance and calls the Colorfy.colors function:
julia> values = [:red, :green, :blue];
julia> colorfy(values, alphas=[0.5, 0.6, 0.7])
3-element Array{RGBA{N0f8},1} with eltype ColorTypes.RGBA{FixedPointNumbers.N0f8}:
RGBA{N0f8}(1.0,0.0,0.0,0.5)
RGBA{N0f8}(0.0,0.502,0.0,0.6)
RGBA{N0f8}(0.0,0.0,1.0,0.7)See the Colorfier docstring for a description of all options.
