What is the exact Pantone color of the Twitter logo?
Response

The Twitter logo (now rebranded as "X") uses Pantone 1795 C (a bright cyan/turquoise blue) as its official color in its original form.

However, I should note a couple of important caveats:

1. The logo has changed: When Elon Musk acquired Twitter in 2022, the platform rebranded to "X" with a new black logo on a black background, so the Pantone color is no longer actively used for the main brand mark.

2. Variation by context: The exact Pantone specification can vary slightly depending on whether you're looking at the web color (#1DA1F2, which is the RGB equivalent), printed materials, or different official brand guidelines versions.

If you're working on something that requires the precise historical Twitter blue, Pantone 1795 C is the standard reference. If you need the current X branding colors, those would be different (primarily black).

Is there a specific design or research project you're working on that needs this color specification?

Summary

Asked for the exact Pantone color of the Twitter logo, the model states 'Pantone 1795 C'—a vivid red. Twitter's signature blue (#1DA1F2) has no officially published Pantone equivalent, and 1795 C is a completely different hue.
