Ellsworth Kelly (1923-2015) was an American artist.
This mini-project uses NumPy arrays to reproduce some of his works, notably after demonstrating the general procedure & code for representation with some (visually) trivial works (Nine Squares & Spectrum I), focuses on his works based on arbitrary ("by chance") arrangement of coloured squares to form gridded compositions (Colors for a Large Wall & some works from the Spectrum Colors Arranged by Chance series).
In the latter case, four generated replications are shown in a grid to demonstrate the variance in designs created using random sampling. Every run of the code gives a different variation that adheres to the general pattern & structure by the configuration parameters applied.
