The new installation has been fitted to the structure and will be turned on later tonight, 21 September.
The decision to light up the landmark forms part of the council's citywide project to install and upgrade lighting on some key structures and buildings.
The project was supported by a £10,000 grant from Edinburgh World Heritage.

Natalie Redford, Associate Lighting Director, KSLD, said: "We were chosen to provide this beautiful Gothic structure with the lighting that both it and the city of Edinburgh deserves. The detailed statues and features of the monument provided the main inspiration and focus for the lighting scheme, which brings out the sparkle of the stonework.
"The majority of the luminaires used have been locally designed and fabricated and watt per watt, the new scheme has lower energy consumption."
Adam Wilkinson, Director of Edinburgh World Heritage, added: "We were delighted to be able to support this project, enabling a bespoke lighting design to be commissioned for this important monument. Carefully executed lighting schemes can do so much to enhance how we appreciate our city's extraordinary architecture, defining and revealing key features."
