Print available themes using available_themes():

Each theme has a corresponding theme_* function that allows you to customize every aspect of the theme.
draw_scatter(
x, y,
theme = theme_whitegrid(
grid_col = "blue", zerolines_col = "red", zerolines_lwd = 2.0)
)8.2 Color palettes
rtemis includes a number of builtin color palettes, along with a few functions to create, manipulate, and preview colors.
get_palette() [1] "ucsfCol" "pennCol" "imperialCol"
[4] "stanfordCol" "ucdCol" "berkeleyCol"
[7] "ucscCol" "ucmercedCol" "ucsbCol"
[10] "uclaCol" "ucrColor" "uciCol"
[13] "ucsdCol" "ucCol" "scrippsCol"
[16] "caltechCol" "cmuCol" "princetonCol"
[19] "columbiaCol" "yaleCol" "brownCol"
[22] "cornellCol" "hmsCol" "dartmouthCol"
[25] "usfCol" "uwCol" "jhuCol"

[52] "microsoftCol" "pantoneBalancingAct" "pantoneWellspring"
[55] "pantoneAmusements" "grays" "rtCol1"
[58] "rtms" Let’s use previewcolor() to look at a selection of the available palettes:
previewcolor(get_palette("imperialCol"), "Imperial")
previewcolor(get_palette("ucsfCol"), "UCSF")
previewcolor(get_palette("pennCol"), "Penn")
previewcolor(get_palette("stanfordCol"), "Stanford")
previewcolor(get_palette("berkeleyCol"), "Berkeley")
previewcolor(get_palette("firefoxCol"), "Firefox")
8.3 System Defaults
You can optionally set system defaults by running the following lines in R or adding them to your .Rprofile file, which is usually found in your home directory. For example, to default to the “darkgrayigrid” theme (works well with a dark VS Code or RStudio theme), you can use the following:
options(rtemis_theme = "darkgrayigrid")
options(rtemis_palette = "rtms")
options(rtemis_font = "Geist")The first line sets the theme for all draw_* functions that support it, and the second line defines the default palette, which works with both light and dark themes.
