Behold, below, Klein Blue — Yves Klein’s famous 1959 painting.
Here is how the Tate Collection describes it:
In 1947, Klein began making monochrome paintings, which he associated with freedom from ideas of representation or personal expression. A decade later, he developed his trademark, patented colour, International Klein Blue (IKB). This colour, he believed, had a quality close to pure space, and he associated it with immaterial values beyond what can be seen or touched. He described it as ‘a Blue in itself, disengaged from all functional justification’.
In contrast to the Klein Bottle, it is two-dimensional. I will leave it to the reader to draw the parallels to Peter (but offer “disengaged from all functional justification” as a clue).
