GPT-3.5 is green:

GPT-4 was originally black. Now it's purple:

What will the next color be?

Resolves:

• 100% to the option whose HTML color is closest to the new logo color.

  • If there are multiple colors equally distant, resolves equally to each.

• This market does not resolve Other, even if the nearest color answer is distant.

• At end of 2024, if there is no new logo color, resolves to the special option "No new color is ever issued".

Add colors whose names are listed here. All other colors are disallowed. When OpenAI announces a new LLM model with logo color different from green, purple, or black and is available to me on ChatGPT, I will calculate the Logo Color as the average color masked over the part that varies. If OpenAI changes their logo and the color doesn't vary between models, I will calculate the average color of the entire image. If transparency is used, I will consider the final rendered color using the default theme.

I will subscribe for a maximum of $200 to test it myself. If it is more expensive than that, I will rely on news articles revealing the color.

In the current OpenAI logo, the "part that varies" is the circular background and not the white foreground; so if the next foreground is dark it will be ignored.

Colors added after announcement do not qualify. Color distance uses the taxicab metric on RGB values mapped to the color. I will use the tweet announcement for precise timing, but a timestamp on the OpenAI site or archive.org could also qualify if earlier.

If you are a moderator and a possible color change has occurred, please close my market for trading and ping me.
