This makes a simple ggplot with boxes side by side of each color in a vector. Numbers along the top show the position of the color in the vector. Optional labels are shown with the name or hexcode of each color; if ggfittext is installed, the labels will be scaled to fit in the rectangles.
color_prev(
colors,
labels = TRUE,
label_color = "black",
border = FALSE,
border_color = "white",
border_size = 0.5
