Colourise.sg was developed in Singapore by a company called GovTech during a January hackathon. According to the creators of the project Algorithmia produced colorized image that lacked intensity, which makes the final product appear inauthentic. The goal of Colourise was to create a program that was specifically trained to colorize old Singaporean photos. The creators did this by training the tool with historical images from Singapore. In contrast, Algorithmia was trained using 1.3 million images from ImageNet, a database often used by researchers at Stanford and Princeton specifically to train AI.
