Deloitte came up with basic design of their current logo in 2003. The primary change was to add the green dot. Deloitte says that this reminds people that Deloitte is here and ready to be remembered.
Deloitte updated the logo on June 15, 2016. They called it a brand refresh. This is most likely because other big 4 accounting firms have updated their logos since Deloitte last updated theirs. They pointed to the number of things that have changed since the initial creation in 2003.
Instead of blue and green the logo is now black lettering with the green dot. The green dot remains the same. This is probably to reflect Deloitte’s professionalism as blue and green is more of a passive color pairing. There is also styling where the font for the logo is white with the green dot.
