```{r, include=FALSE}

library(feathers)

library(dplyr)

```



This package contains colour palettes inspired by the plumage of Australian birds. For species exhibiting sexual dimorphism (i.e. males and females look different), I have used female colours. Research on birds has historically been biased towards males, and the choice to use female colours in this package is my way of highlighting the often-overlooked beauty of female birds.



## Installation



This package is hosted on GitHub and can be installed using the devtools package:



```{r, message=FALSE, warning=FALSE, echo = TRUE, results='hide'}

devtools::install_github(repo = "shandiya/feathers", ref = "main")

```



## How to use `feathers`



Colour palettes are stored as a list called `feathers_palettes`, and can be accessed thus:



```{r}

library(feathers)

names(feathers_palettes)

```



`get_pal` returns the chosen palette as a vector of hex colour codes.



```{r}

get_pal("eastern_rosella")

```



`print_pal` displays the colour palette.



```{r, fig.height=1, fig.width=7, fig.align='center'}

eastern_rosella <- get_pal("eastern_rosella")

print_pal(eastern_rosella)

```



## Examples



Colour palettes can be used for data visualisation in base `R` and `ggplot2`.



```{r message=FALSE, warning=FALSE, out.width=c('50%', '50%'), fig.show='hold'}



# base R

library(palmerpenguins)

plot(penguins$flipper_length_mm, penguins$body_mass_g, col = get_pal("rose_crowned_fruit_dove")[factor(penguins$species)], pch = 19)



# ggplot2

library(ggplot2)

library(palmerpenguins)

ggplot(penguins) +

  geom_point(aes(flipper_length_mm, body_mass_g, colour = species)) +

  scale_colour_manual(values = get_pal("rose_crowned_fruit_dove"))



```

## Continuous palettes



The qualitative colour palettes in `feathers` may be converted into sequential or diverging palettes for different types of data visualisation using the `colorRampPalette()` function.



### Sequential palette



```{r, results = FALSE}

# choose end colours

seq_col <- get_pal("eastern_rosella")[c(2,7)]  



# create a gradient of 50 shades in between the selected colours 

colorRampPalette(seq_col)(50)

```



```{r, echo = FALSE, fig.height=2, fig.width=10, fig.align='center'}

print_pal(colorRampPalette(seq_col)(50))

```



### Diverging palette



```{r, results = FALSE}

# choose end and middle colours

div_col <- get_pal("oriole")[c(1,5,10)]



# create a gradient of 50 shades in between the selected colours 

colorRampPalette(div_col)(50)

```



```{r, echo = FALSE, fig.height=2, fig.width=10, fig.align='center'}

print_pal(colorRampPalette(div_col)(50))

```



## Accessibility



There are many tools and packages which simulate different types of colour vision deficiency, such as [Viz Palette](https://projects.susielu.com/viz-palette), [colorblindcheck](https://jakubnowosad.com/colorblindcheck/index.html), [prismatic](https://emilhvitfeldt.github.io/prismatic/), and [colorblindr](https://github.com/clauswilke/colorblindr). You may find these helpful in guiding your decisions about which colours to include in your visualisation to make it accessible to as many people as possible. Happy plotting!
