Cool Yellow (Bright Light Yellow) is having a moment
While I keep meaning to update my 2018 article Hard-to-Find LEGO Colors (and what to do about it), it clearly indicated that 226Cool YellowBright Light Yellow was a “rare” color since it was only available in 8 of the 24 parts used in my analysis. (While I didn’t update the article in 2019, you would have found that it was up to 14/24 parts, nearly entering the “uncommon” category.)
Suffice to say, the newly released Creator Expert #10271 Fiat 500 set has put the previously rare color on the map, since it is used as the color for the car’s brick-built exterior.
The set incudes 40 parts which are new for 2020 in the 226Cool YellowBright Light Yellow color. Among those new parts are 13x 1×3 Plate (Part 3623), 5x 2×4 Plate (Part 3020), 3x 1×4 Tile (Part 2431), & 9x 1×8 Tile (Part 4162). This brings it up to 18/24 parts, putting it well within the “uncommon” category, and on track to become a common color soon.
The Fiat 500 costs $89.99 (€79.99 / £74.99) for 960 pieces (or a cool $0.09 per part.)
