Here is an example. Text color is black by default.

library(voronoiTreemap)

data(ExampleGDP)
gdp_json <- vt_export_json(vt_input_from_df(ExampleGDP))
vt_d3(gdp_json, legend=TRUE)
voronoi r

WOO HOO! I'm pretty happy with myself on this one. I digress.

To set the legend text color change this -> '#b21e29' in the following code:

library(voronoiTreemap)
library(htmlwidgets)
library(dplyr)

data(ExampleGDP)
gdp_json <- vt_export_json(vt_input_from_df(ExampleGDP))

# try number 70032536587832
(plt = vt_d3(gdp_json, legend=TRUE) %>% 
    onRender("function(el){
                legends = el.lastChild.lastChild;
                legends.lastChild.setAttribute('style', 'fill: #b21e29;');
             }"))
