The museum, which is the most visited UK museum outside of London, will reopen on July 11 after Fitch was appointed to create a brand identity to reflect the building's new interior.
The museum contains a large collection of natural history, archaeology, armour and civic art exhibits, which the trustees said would now reopen with improved visitor facilities, additional gallery space and 50% more works.
Fitch was briefed to create an identity that reflected the "rebirth" of the museum but did not interfere with the integrity and impact of the Edwardian building.
The company, which is owned by network WPP, said it chose a distinctive typography and lime green palate to make an "uncomplicated and timeless statement" about the museum's array of exhibits.
David Roberts, design director at Fitch, said: "From the outset, we realised the key was to stop thinking of Kelvingrove as an institution, and start thinking about it as a leisure and destination brand competing for the hearts, mind and spend of consumers who have a diverse range of options in retail and entertainment."
The redesign will also incorporate over 750 signs across three floors of the museum, which is split into two themes, Expression and Life.
Fitch said the redesign would also allow expansion for shops and cafes if needed in the future.
The museum was voted the city's favourite building by Glaswegians in 1998.
Fitch announced in May it was to aid Russia's Gradient conglomerate expand its business from one to 700 stores by 2012.
