"It's a huge loss, but I'm grateful for the memories."
First Minister John Swinney said he was saddened to hear about Sir Geoff's death.
He said: "Sir Geoff Palmer was a pioneer and an outstanding intellectual. He had a hugely positive impact on Scotland and will be sorely missed."
Scottish Labour leader Anas Sarwar said the academic was "a gentleman, a pioneer and an intellectual giant" who would be dearly missed.

Sir Geoff moved to London from St Elizabeth, Jamaica, in 1955, ing his mother in the city.
After studying at the University of Leicester, he completed his PhD in grain science and technology tly with Heriot-Watt College and the University of Edinburgh in the 1960s.
Following a spell in Surrey, he returned to Heriot Watt in 1977, going on to become Scotland's first black professor in 1989 before eventually retiring in 2005.
Sir Geoff's academic work saw him invent the barley abrasion process - which involves deliberately damaging the protective husk of grains to speed up the process of malting.
His efforts won him the American Society of Brewing Chemists Award of Distinction, an honour dubbed the Nobel prize of the beer world, while the success of his discovery attracted funding that established the International Centre for Brewing and Distilling as part of the Heriot-Watt campus.
'Lasting impression on Edinburgh'

Sir Geoff was also known as a ionate advocate for the rights of black communities, work which saw him invited by Edinburgh City Council to chair a review group looking at the city's colonial legacy.
The group presented a number of recommendations, including that the city council should apologise for Edinburgh's past role in slavery and colonialism.
In 2014 Sir Geoff was knighted for services to human rights, science and charity and four years later he he was appointed Jamaica's first Honorary Consul in Scotland.
He was the 2020 recipient of the Jamaican national honour, the Order of Distinction (Commander Class) and in 2021 was appointed chancellor of Heriot Watt university.
Last year he was awarded Scotland's highest royal honour, the Order of the Thistle, in recognition of his significant contributions to national life and public service.
Edinburgh's Lord Provost Robert Aldridge called Sir Geoff a "true inspiration" who will "leave a lasting impression on Edinburgh".
He added: "In chairing the Edinburgh Slavery and Colonialism Legacy Review Sir Geoff made a vital contribution to recognising and profiling the capital's links with slavery and colonialism in the public realm.
"I know Sir Geoff's legacy in academia and activism will live on for years to come, inspiring future generations. He will be dearly missed – my thoughts are with his friends, family and all those who knew him."
