Lego is a brand of expensive plastic building toys. Lego is great. I loved it as a child and I still love it, though I no longer know how to play with it. Lego Bionicle has shaped a lot of my tastes.
I need a lot of sand-colored parts (apparently, it's called tan) to build a cool desert-themed building. I have only built the entrance to it due to lack of parts.
The best Lego theme is, indubitably, Bionicle.
In this article, I have done a detailed analysis of which colors are most common in sets from the last 5 years. This has been done before, which is why I took the analysis one step further and looked at the 24 most common basic bricks/plates/tiles as a way of gaining insight into not only how many parts are made in each color, but which colors are offered in the widest selection of useful parts.
