For example, a carrot will have an orange color in most images. Bananas will be either greenish or yellowish. It contains 723 images from the internet distributed in 20 categories. Each image has an object and a white background.\n\nSource: [https://github.com/saeed-anwar/ColorSurvey#dataset](https://github.com/saeed-anwar/ColorSurvey#dataset)\nImage Source: [https://github.com/saeed-anwar/ColorSurvey](https://github.com/saeed-anwar/ColorSurvey)","description_withheld":null,"homepage":"https://github.com/saeed-anwar/ColorSurvey","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/image-colorization-a-survey-and-dataset","title":"Image Colorization: A Survey and Dataset","first_author":"Saeed Anwar","url":null},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Colorization","url":"/task/colorization","datasets_with_task":"/datasets/task/colorization"}],"languages":[],"variants":["NCD"],"data_loaders":[{"repo":"https://github.com/saeed-anwar/ColorSurvey","url":"https://github.com/saeed-anwar/ColorSurvey","frameworks":[]}],"num_papers_in_archive":6,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
