Twitter's original blue represented open communication, while the rebranded X uses stark black and white to signal a bold, unfiltered new identity.
The original Twitter blue (#1DA1F2) was chosen to evoke the open sky and the freedom of a bird in flight — perfectly aligned with the bird logo and the platform's original mission of open conversation. After Elon Musk's acquisition and rebrand to 'X' in 2023, the palette shifted to pure black and white, abandoning the friendly blue for a stark, maximalist identity that signals disruption and edge.
