How to hard code the color for the displayed variable in plotly pie chart?

General

Do we have something similar to our ggplot where
we define the color panel for each variable ?

scale_manual <- function(...){
ggplot2::manual_scale(
"fill",
values = setnames(c("green","red","blue","yellow","grey"),
c("var1","var2","var3","var4","var5")),
...
)
}

Please consider an reprex below:

library(plotly)

USPersonalExpenditure <- data.frame("Categorie"=rownames(USPersonalExpenditure), USPersonalExpenditure)
data <- USPersonalExpenditure[,c('Categorie', 'X1960')]

p <- plot_ly(data, labels = ~Categorie, values = ~X1960, type = 'pie') %>%
  layout(title = 'United States Personal Expenditures by Categories in 1960',
         xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
         yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))

#trial 1
plot_ly(data, labels = ~Categorie, values = ~X1960, type = 'pie', marker = list(color = rainbow(5))) %>%
layout(title = 'United States Personal Expenditures by Categories in 1960', 
xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))

# trial 2
plot_ly(data, labels = ~Categorie, values = ~X1960, type = 'pie', marker = list(color = brewer_pal(5, "Set3"))) %>%
layout(title = 'United States Personal Expenditures by Categories in 1960', 
xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))
