  3. Interactive Data Visualization with plotly in R

Exercise

Alternative color formats

R has a large number of named colors, but sometimes you need a color that isn't named. For example, what if your organization's specific shade of blue is somewhere between "navy" and "dodgerblue4"? Luckily, plotly allows you to specify colors using other formats, including RGB, RGBA, HEX, HCL, HSL, and HSV.

In this exercise, you will change the histogram's color to using HEX and RGB formats.

Note that plotly has already been loaded for you.
