1. Use the cursor to select object to print in the console.

# Highlight objects by cursor to show the contained colors
pick_color()

# Change output styles, "ribbon" or "mosaic"
pick_color(type = "r")

# Change the length of the color blocks
pick_color(blank.len = 1)
Pick colors
Pick colors

2. Use print_color to print color literals, palettes and ggplot2 objects.

Note: the colors may appear not distingushable in the html version, but they always work fine in console.

print_color(c("red", "navy", "pink", "#E58700", "limegreen"))
#> 
#>  ------ c red navy pink #E58700 limegreen ------
#>                

print_color(c("red", "navy", "pink", "#E58700", "limegreen"), 
            type = "r")
#> 
#>  ------ c red navy pink #E58700 limegreen ------
#> red                 
#> navy                
#> pink                
#> #E58700             
#> limegreen           


print_color(palette(rainbow(6)), blank.len = 1)
#> 
#>  ------ palette rainbow(6) ------
#>         

print_color(palette(rainbow(6)), type = 'r')
#> 
#>  ------ palette rainbow(6) ------
#> red                 
#> yellow              
#> green               
#> cyan                
#> blue                
#> magenta             


p1 <- ggplot(mpg) +

3. Use open_sample() to open a sample file to have an instant try.

# Open the pre-defined test file
