Was the Launch Entry Suit, the pumpkin suit, the first time any space agency used the color International Orange in anything intended to go into space?

From International orange; Astronautics:

The Advanced Crew Escape Suits pressure suits worn by NASA astronauts and the previous Launch Entry Suit use this color,4,5 as opposed to the lighter tone of safety orange used by the United States Air Force's high-altitude suits. This was also planned for the new Constellation Space Suit systems that were to be flight-ready by 2015.

    $\begingroup$ Is "international orange" the intent of those suits? Or is it visibility in possible low visibility scenarios? I think most color choices are functional. $\endgroup$ Commented Sep 14, 2019 at 2:26

    $\begingroup$ The Wikipedia article does not explain what's supposed to be "international" about the color. In fact it seems to me to be entirely made up -- none of the references it provides support that name in particular. $\endgroup$ Commented Sep 14, 2019 at 13:30

    $\begingroup$ @MagicOctopusUrn Notably, the so called "black boxes" on aircraft, despite the name, are also that color for the same reason. $\endgroup$ Commented Sep 14, 2019 at 18:01

Yuri Gagarin wore the first space suit in 1961, the SK-1. It was orange.

No, it was not. The Apollo parachutes had orange gores.
