## ColorSchemes
This package provides a collection of colorschemes:
- scientifically devised colorschemes from ColorBrewer, CMOcean, ScientificColorMaps, ColorCet, and Seaborn
- popular old favourites such as _viridis_, _inferno_, and _magma_ from MATPlotLib
- old masters' colorschemes, such as _leonardo_, _vermeer_, and _picasso_
- variously themed colorschemes such as _sunset_, _coffee_, _neon_, and _pearl_
Note that the schemes contained here are a mixture:
- some are high quality color maps with consistent perceptual contrast over their full range
- others are designed for general purpose and informal graphics work
Choose colorschemes with care! Refer to Peter Kovesi's [PerceptualColourMaps](https://github.com/peterkovesi/PerceptualColourMaps.jl) package, or to Fabio Crameri's [Scientific Colour Maps](http://www.fabiocrameri.ch/colourmaps.php) for more information.
If you want to make more advanced ColorSchemes, use linear-segment dictionaries or indexed lists, and use functions to generate color values, see the `make_colorscheme()` function in the [ColorSchemeTools.jl](https://github.com/JuliaGraphics/ColorSchemeTools.jl) package.
## Basic usage
```julia
] add ColorSchemes
using ColorSchemes
ColorSchemes.Purples_5
# => a ColorScheme
colorschemes[:Purples_5]
# => a ColorScheme
ColorSchemes.Purples_5.colors
# => array of five RGB colors
ColorSchemes.Purples_5.colors[3]
# => the third color in the colorscheme
get(ColorSchemes.Purples_5, 0.5)
# => the midway point of the colorscheme
colorschemes
# => Dict{Symbol, ColorScheme} with 983 entries
findcolorscheme("purple")
# => display list of matching schemes
ColorScheme([colorant"red", colorant"green", colorant"blue"])
# new colorscheme from Colors.jl named colors
get(ColorSchemes.darkrainbow, range(0.0, 1.0, length=20)) |> ColorScheme
# new colorscheme by resampling existing
