ColorVintner

A Julia package for exploring and visualizing ColorBrewer color schemes using Makie.

Features

• Comprehensive Color Scheme Access: Access to all ColorBrewer sequential, diverging, and qualitative color schemes
• Interactive Visualization: Create beautiful color bar plots using Makie
• Scheme Exploration: Browse and examine color schemes with detailed information
• Export Capabilities: Save plots as PDF files for publication
• Organized Display: Split large scheme collections into manageable parts

Installation

using Pkg
Pkg.add("ColorVintner")

Quick Start

using ColorVintner

# Show all available scheme names
show_all_scheme_names()

# Get information about a specific scheme
list_scheme_colors_in_rbg(:Blues_5)

# Create a DataFrame with all schemes and their hex colors
df = list_schemes_colors_in_hex()

# Plot a few schemes
plot_color_bars([:Blues_5, :Reds_5, :Greens_5])

# Create comprehensive plots for all categories
plots = plot_schemes_by_category()

Main Functions

Exploration Functions

• show_all_scheme_names(): Print all available color scheme names
• list_scheme_colors_in_rbg(scheme_name): Display detailed information about a specific scheme
• list_schemes_colors_in_hex(): Create a DataFrame with all schemes and their hex representations

Plotting Functions

• plot_color_bars(schemes): Create color bar plots for a list of schemes
• plot_schemes_by_category(): Create comprehensive plots for all categories
• plot_sequential_schemes_split(): Create plots for sequential schemes (split into 4 parts)
• plot_diverging_schemes_split(): Create plots for diverging schemes (split into 3 parts)
• plot_qualitative_schemes_split(): Create plots for qualitative schemes (split into 2 parts)

Distribution Functions

• show_sequential_distribution(): Show how sequential schemes are distributed
• show_diverging_distribution(): Show how diverging schemes are distributed
• show_qualitative_distribution(): Show how qualitative schemes are distributed

Examples

Basic Usage

using ColorVintner

# Plot a few schemes with custom settings
plot_color_bars([:Blues_5, :Reds_5, :Greens_5], 
                schemes_per_row=3, 
                save_path="my_plot.pdf",
                plot_title="My Color Schemes")

Comprehensive Visualization

# Create all category plots and save to a directory
plots = plot_schemes_by_category(save_dir="./color_plots")

Scheme Information

# Get detailed information about a scheme
colors = list_scheme_colors_in_rbg(:Blues_5)

# Get all schemes as a DataFrame
df = list_schemes_colors_in_hex()
first(df, 10)  # Show first 10 schemes

Color Scheme Categories

Sequential Schemes

Sequential color schemes are designed for data that progresses from low to high values. They use a single hue that varies in lightness and saturation.

Diverging Schemes

Diverging color schemes are designed for data that has a meaningful center point (like zero). They use two different hues that meet at a neutral color.

Qualitative Schemes

Qualitative color schemes are designed for categorical data. They use distinct colors that are easily distinguishable from each other.

Dependencies

• CairoMakie: For high-quality plotting
• ColorSchemes: For access to ColorBrewer schemes
• Colors: For color manipulation
• DataFrames: For data organization
• Makie: For plotting framework
