Build a smooth RGB rainbow data frame

Produces a tibble of r, g, b channel values walking through the six canonical rainbow segments (red -> yellow -> green -> cyan -> blue -> purple -> red). The argument selects which segments to include and in which order.

Usage

rgb_colors_for_plot(colors_changes_vector = c(3:6, 1))

Arguments

colors_changes_vector

Integer vector with values in 1:6. Default c(3:6, 1) gives a green -> red sweep.

Value

A tibble::tibble() with columns r, g, b.

Examples

head(rgb_colors_for_plot())
#> # A tibble: 6 × 3
#>       r     g     b
#>   <dbl> <dbl> <dbl>
#> 1     0   255     0
#> 2     0   255     1
#> 3     0   255     2
#> 4     0   255     3
#> 5     0   255     4
#> 6     0   255     5
