Google are now launching a new version of Gmail, Gmail Blue.
This new version of Gmail has been made to be intimate, intuitive, realistic and organic. Google wanted to completely redesign and recreate Gmail but also keep it exactly the same. And what they've come up with is Gmail Blue.
The compose button is now blue, bold face is blue, underline is blue and italics is blue. When writing your email you get a light blue background with blue text. It's Gmail, only bluer.
Gmail Blue is the new Gmail which Google are hoping everyone will adopt and love. Or it's just another one of Google's April fools' joke ;)
