r- ggplot2 color and fills not functioning : <p>I'm trying to visualize a single scatterplot using ggplot2 and adjust the colors to make the graph more visually appealing, however, the <code>colors</code> and <code>fill</code> functions are not populating the colors I want. </p>

<p>For reference I've looked through <a href="http://r-statistics.co/ggplot2-Tutorial-With-R.html" rel="nofollow noreferrer">this very helpful link</a> in addition to the <a href="https://github.com/rstudio/cheatsheets/blob/master/data-visualization-2.1.pdf" rel="nofollow noreferrer"><code>tidyverse</code> cheatsheets for ggplot2</a>, neither of which cover how to change the color of one single variable.</p>

<p>See below dummy data set with chart example below showing desired colors as the variable names:</p>

<pre><code>dfRaw&lt;- as.data.frame(cbind(var1= rnorm(10,11,3), var2= rnorm(10,12,2)))

rawPlot&lt;- ggplot(dfRaw, aes(x= var1, y= var2, fill= 'skyblue', color= 'skyblue')) + geom_point()
&gt; rawPlot
</code></pre>

<p>In the above, <code>skyblue</code> is being desginated as the <code>fill</code> and <code>color</code> but is neither. This happens whether I use one or both designations. I'm looking for advice on how to fix this in addition to directions to a <em>color list</em> for <code>ggplot2</code>. </p>
