`mexicolors`: A Mexican politics-inspired color palette generator

Building on Philip Waggoner’s approach to designing color palettes in the amerika package, the mexicolors package offers a variety of a Mexican politics-inspired color palettes for a host of applications both in and out of politics.

Palette options range from only a few colors to several colors, but with discrete and continuous options to offer greatest flexibility to the user. mexicolors allows for a range of applications, from mapping brief discrete scales to continuous interpolated arrays including dozens of shades graded from green to red. See below for a list of the palettes followed by a few political and non-political examples.

Installation

Dev:

{r } devtools::install_github("alexplatasl/mexicolors") library(mexicolors)

Use

Users simply supply the name of the desired palette in the main function mexico_palette(), along with the number of colors desired from the palette (e.g., only 4 from a 5-color palette), and whether “continuous” or “discrete” type mapping is desired.

Palettes

morena: two shades of red and two shades of grey.
pri: four colors including green, white, grey, and red.
pan: four colors including three shades of blue and one shade of white.
prd: five colors including two shades of yellow, one shade of white, and two shades of grey.
cuatroT: eight colors including two shades of red, two shades of yellow, two shades of gray, and two shades of green.
ine: four colors including whine, mexican pink, grey, and black.
pvem: six colors including three shades of green, yellow, red, and black.
mc: eight colors including four shades of orange and four shades of gray..

Displaying each palette

{r } mexico_palette("cuatroT")

{r } mexico_palette("ine")

{r } mexico_palette("morena")

{r } mexico_palette("pri")

{r } mexico_palette("pan")

{r } mexico_palette("prd")

{r } mexico_palette("pvem")

{r } mexico_palette("mc")

Interpolating between existing colors based on the palettes using the “continuous” `type`

{r } mexico_palette(n = 50, name = "cuatroT", type = "continuous")

{r } mexico_palette(n = 50, name = "ine", type = "continuous")

{r } mexico_palette(n = 50, name = "morena", type = "continuous")

{r } mexico_palette(n = 50, name = "pri", type = "continuous")

{r } mexico_palette(n = 50, name = "pan", type = "continuous")

{r } mexico_palette(n = 50, name = "prd", type = "continuous")

{r } mexico_palette(n = 50, name = "pvem", type = "continuous")

{r } mexico_palette(n = 50, name = "mc", type = "continuous")

Example Political Cases (Discrete and Continuous)

```{r } library(tidyverse) # Continuous: “ideology” on a 100 point scale (hypothetical for demo purposes only) data1 <- data.frame(sample(1:100, 3000, replace=TRUE))

data1 <- data1 %>% rename(id = sample.1.100..3000..replace…TRUE.) %>% as.data.frame()

ggplot(data1, aes(id)) + geom_bar(fill=mexico_palette(n = 100, name = “cuatroT”, type = “continuous”)) + labs(x = “Political Ideology (Liberal - Conservative)”, y = “Count of Respondents”) + theme_bw()

### Non-Political Cases (5 and 7 level palettes)

```{r }
library(tidyverse)

# 5-level (discrete) palette
ggplot(diamonds, aes(factor(cut), fill = factor(cut))) +
  geom_bar() + 
  scale_fill_manual(values = mexico_palette("cuatroT", 5, "discrete")) +
  theme_bw()

```{r } library(tidyverse)

7-level (discrete) palette

ggplot(diamonds, aes(factor(color), fill = factor(color))) + geom_bar() + scale_fill_manual(values = mexico_palette(“morena”, 7, “continuous”)) + theme_bw() ```
