# Exploring Van Gogh Palettes in R

#### Van Gogh Palette Package

# ——————————————————————————

# 1. Display a single palette

# ——————————————————————————

# Visualise a discrete palette

vangogh::viz_palette(“StarryNight”)

# Visualise a colorblind-safe palette ( optional)

#

# ——————————————————————————

# 2. Generate colorblind-safe versions

# ——————————————————————————

# Standard palette

pal_orig <- vangogh::safe_vangogh_palette(“StarryNight”) pal_orig

# Colorblind-safe version ( optional)

#

# Compare original vs colorblind palettes ( optional)

#

# ——————————————————————————

# 3. Discrete vs Continuous palettes

# ——————————————————————————

# Discrete palettes: fixed number of colors, best for categorical data

pal_discrete <- vangogh::safe_vangogh_palette(“SunflowersMunich”, type = “discrete”) pal_discrete

# Continuous palettes: interpolate to n colors, ideal for gradients

pal_cont <- vangogh::safe_vangogh_palette(“CafeTerrace”, type = “continuous”, n = 12) vangogh::viz_palette(“CafeTerrace”, type = “continuous”, n = 12)

# ——————————————————————————

# 4. Working with ggplot2

# ——————————————————————————

# 4a. Discrete color scale

ggplot2::ggplot(mtcars, ggplot2::aes(mpg, wt, color = factor(cyl))) + ggplot2::geom_point(size = 3) + vangogh::scale_color_vangogh(“StarryNight”) + vangogh::theme_vangogh(base_size = 14) + ggplot2::labs(title = “Discrete Van Gogh Color Scale Example”)

# 4b. Continuous color scale

ggplot2::ggplot(mtcars, ggplot2::aes(mpg, wt, color = hp)) + ggplot2::geom_point(size = 3) + vangogh::scale_color_vangogh(“Cypresses”, discrete = FALSE) + vangogh::theme_vangogh() + ggplot2::labs(title = “Continuous Van Gogh Color Scale Example”)

# 4c. Fill scales

ggplot2::ggplot(diamonds, ggplot2::aes(cut, fill = clarity)) + ggplot2::geom_bar() + vangogh::scale_fill_vangogh(“CafeDeNuit”) + vangogh::theme_vangogh() + ggplot2::labs(title = “Discrete Fill Example”)

# Continuous fill example

ggplot2::ggplot(diamonds, ggplot2::aes(carat, price, fill = price)) + ggplot2::geom_tile() + vangogh::scale_fill_vangogh(“StarryRhone”, discrete = FALSE) + vangogh::theme_vangogh() + ggplot2::labs(title = “Continuous Fill Example”)

# ——————————————————————————

# 5. Inspect all palettes programmatically

# ——————————————————————————

# Get tidy data frame of all palettes

all_palettes <- vangogh::vangogh_colors() head(all_palettes)

# With colorblind adjustment ( optional)

#

# List all palette names

names(vangogh::vangogh_palettes)

# ——————————————————————————

# 6. Multi-palette comparison visualisation

# ——————————————————————————

# Compare multiple palettes side-by-side ( optional)

#

# ——————————————————————————

# 7. Additional functions

# ——————————————————————————

# View detailed palette info

vangogh::vangogh_palette_info()
