Hey,

Create a function using colorNumeric.Factor/bins. Then call the function using field for color inside marker function.

Syntax of color* functions: color*(palette, domain,reverse,....)

Ex: 

pal <- colorNumeric(c("green","yellow",,"red"), domain = NULL,reverse = TRUE)
leaflet(quakes) %>% addTiles() %>%
  addCircleMarkers(
    color = pal(sort(ozone$median)),
    stroke = FALSE, fillOpacity = 0.5,
    radius = 2.2
  )
