cgrad(colors, [values];
categorical = nothing, scale = nothing, rev = false, alpha = nothing)
Construct a Colorgradient from `colors` and `values`.
`colors` can be a symbol for ColorSchemes.jl `ColorScheme`s, a `ColorScheme`, a vector of colors, a `ColorGradient` or a `ColorPalette`.
If `values` is an integer, it specifies the numbers of colors chosen equidistantly from the colorscheme specified by colors.
Otherwise vectors are accepted.
For continuous color gradients `values` indicate where between 0 and 1 the colors are positioned.
For categorical color gradients `values` indicate where a color ends and where a new one begins between 0 and 1.
0 and 1 are added to `values` if not already present.
If `rev` is `true` colors are reversed.
`scale` accepts the symbols `:log`, `:log10`, `:log2`, `:ln`, `:exp`, `:exp10` or functions.
If `alpha` is set, it is applied to all colors.
"""

Accepts symbols for Colorschemes.jl `ColorScheme`s, `ColorScheme`s, vectors of colors, `ColorGradient`s and `ColorPalettes`.
If 'n' is provided, `n` colors are chosen equidistantly from the colorscheme.
If `rev` is `true` colors are reversed.

Color attributes
color=theme(scene, :linecolor) sets the color of the line. If no color is set, multiple calls to line! will cycle through the axis color palette. Otherwise, one can set one color per line point by passing a Vector{<:Colorant}, or one colorant for the whole line. If color is a vector of numbers, the colormap args are used to map the numbers to colors.
cycle::Vector{Symbol} = [:color] sets which attributes to cycle when creating multiple plots.
colormap::Union{Symbol, Vector{<:Colorant}} = :viridis sets the colormap that is sampled for numeric colors. PlotUtils.cgrad(...), Makie.Reverse(any_colormap) can be used as well, or any symbol from ColorBrewer or PlotUtils. To see all available color gradients, you can call Makie.available_gradients().
colorscale::Function = identity color transform function. Can be any function, but only works well together with Colorbar for identity, log, log2, log10, sqrt, logit, Makie.pseudolog10 and Makie.Symlog10.
colorrange::Tuple{<:Real, <:Real} sets the values representing the start and end points of colormap.
nan_color::Union{Symbol, <:Colorant} = RGBAf(0,0,0,0) sets a replacement color for color = NaN.
lowclip::Union{Nothing, Symbol, <:Colorant} = nothing sets a color for any value below the colorrange.
highclip::Union{Nothing, Symbol, <:Colorant} = nothing sets a color for any value above the colorrange.
alpha = 1.0 sets the alpha value of the colormap or color attribute. Multiple alphas like in plot(alpha=0.2, color=(:red, 0.5), will get multiplied.
