help you fix your problem I did it this way:
1) In loadWords() map any colour I want to assign to the specific object
code :
function loadWords(){
    var word1 = {
            text: 'word',
            size: 32,
            color:'#FF00FF'
            };
    var word2 = {
            text: 'word2',
            size: 45,
            color:'#3498DB'
            };
    return [word,word2]
    }

  d3.layout.cloud().size([300, 300])
      .words(loadWords())
      ...
      .start();
  function fillColor(d,i){
      return d.color;
  }
        .style("fill", fillColor)

With these it helps I am creating a wordcloud by modifying code from : https://github.com/jasondavies/d3-cloud. I can change the size by modifying w & h but I want to scale the word cloud as the browser window changes. What would be the best method to achieve this? , Solution # 1:
On line 37:
code :
.style("font-size", function(d) { return (d.size) + "px"; })
.style("font-size", function(d) { return (d.size/3) + "vh"; }) // "d.size/3" is an assumption use your appropriate relative width or height.
    .style("font-size", function(d) { return (d.size) + "px"; })
   .attr("class", nameOfClass) // use class names here like 'big-font', 'med-font', 'small-font'

I think the issue was by ths following , You don't include an example of your "wordTfIdf.csv" which would really help to answer this question but I'm from the looks of it it's something like this:
code :
word,tfidf
one, 20
two, 30
three, 40
four, 50
five, 60
six, 70
seven, 80
nine, 90
// give d3.csv two functions
// the first to parse each row
// the second to draw the cloud
d3.csv("wordTfIdf.csv", function(d) {
    return { // for each csv row return an object with text and size
      text: d.word,
      size: +d.tfidf // cast this to a number with +
    }
  },
  function(data) {
    d3.layout.cloud().size([960, 600]).words(
      data // data is already in the correct format
    )

help you fix your problem It depends on what class() df_all_cloud is. I just reordered the columns of a data.frame with row names using:
code :
 library(dplyr)

 samp2 <- rownames(df_all_cloud) #grab rownames

 df_all_cloud <- df_all_cloud %>%
    select("RustNonSwing",
           "RustSwing",
           "NonRustSwing",
           "NonRustNonSwing") %>% #Reorder columns/remove rownames
    mutate_if(function(x) is.factor(x), 
              funs(as.numeric(as.factor(.))-1)) #Make sure things are numeric

 rownames(df_all_cloud) <- samp2 #Add the rownames back

 library(wordcloud)

 comparison.cloud(df_all_cloud, random.order=FALSE, 
             colors = c("hotpink2","orange2","limegreen","lightslateblue"),
             title.size=1.5, max.words=200)
