Theme Lab: Tune Family, Preset, and Rhythm

What Is This Page For?

Use this page to choose a visual direction before you retrofit or create vignettes. You can tune one parameter at a time and immediately see the effect on hierarchy, contrast, and page rhythm.

Start with family and preset, then tune style, then adjust content width. That order gives the fastest path to a coherent page.

How Do You Use It?

  1. Pick a family for color character.
  2. Pick a preset for ground/surface mood.
  3. Toggle style intensity to set structural emphasis.
  4. Adjust content width to match prose density.
<div class="theme-lab__controls">
  <div>
    <label for="albers-family">Family</label>
    <select id="albers-family" data-albers-control="family">

What Does Each Control Change?

Can You Validate The Palette Quickly?

pal <- albersdown::albers_palette(params$family)
stopifnot(
  identical(names(pal), c("A900", "A700", "A500", "A300")),
  all(nzchar(unname(pal)))
)
knitr::kable(data.frame(tone = names(pal), hex = unname(pal)), format = "html")
tone hex
A900 #C22B23
A700 #DC3925
A500 #E44926
A300 #E35B2D

Copy Into YAML

params:
  family: red
  preset: study
  base_size: 13
  content_width: 80
  style: minimal

Example Plot

mtcars$grp <- factor(mtcars$cyl)
stopifnot(length(levels(mtcars$grp)) >= 3)

ggplot(mtcars, aes(wt, mpg, colour = grp)) +
  geom_point(size = 2.2) +
  labs(
    title = "Theme Lab preview",
    subtitle = "Tune family + preset + style, then copy YAML"
  )
