R-plotly中线条的颜色的名称是什么？

Question

I'm setting manually the color of lines in plot using plotly. I would like to know which are the names of the colors available to use.

I already know the names of the "basic" colors.

As: c("red","blue","green", "yellowgreen",...)

library(dplyr)
library(plotly)
library(magrittr)


color_line = "yellowgreen"

mtcars %>% count(gear) %>%
  plot_ly() %>%
  add_trace(x = ~gear, y = ~n, name = "Gear",type = "bar") %>%
  add_trace(x=~gear, y= ~cumsum(n/sum(n)), type ="scatter",mode="markers+lines" ,
            line=list(shape="spline", color = color_line), 
            marker = list(color = ""), 
            name = "Cumsum",yaxis = "y2") %>%
  layout(yaxis2 = list(tickfont = list(color = color_line),
                       overlaying = "y",
                       side = "right"
                        )
        )

Does someone know all the names of colors?

Greetings all.

Here is a full list of named colors:

Answer 2

You don't need to use the names, from plotly's docs:

a color may be specified as:

• A hex string (eg '#ff0000')
• An rgb/rgba string (eg 'rgb(255,0,0)')
• An hsl/hsla string (eg 'hsl(0,100%,50%)')
• An hsv/hsva string (eg 'hsv(0,100%,100%)')
• A named CSS color

I'm not a design expert so whenever I need to choose colors I pick them from a palette or from the picker at htmlcolorcodes . They have a lot of info on how to choose colors also.
