As an analyst, I turned to data for answers. I found a dataset on Rebrickable (a site that shows you which Lego sets you can build from the sets and pieces you already own), which contained information on the color, number, and type of pieces in each Lego set for the past 67 years. I used Plotly and Mode Python Notebooks to explore the data.
This is wonderful. The findings:
Perhaps not surprisingly, Lego’s color palette has expanded over the decades. Until the 1990s, almost every piece was one of the top ten colors; now only about 80% are.
