By combining with the SDSS data as a local counterpart for comparison, we construct a large sample of galaxies that spans wide ranges in environment, time, and stellar mass (or luminosity). We find that colours of galaxies, especially those of faint galaxies ($M_V>M_V^*+1$), change from blue to red at a break density as we go to denser regions. Based on local and global densities of galaxies, we classify three environments: fi","authors_text":"Ichi Tanaka, Kazuhiro Shimasaku, Keiichi Umetsu, Masayuki Tanaka, Nobuo Arimoto, Sadanori Okamura, Tadayuki Kodama, Toru Yamada","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2005-06-29T03:58:45Z","title":"The Build-up of the Colour-Magnitude Relation as a Function of Environment"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0506713","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0a52e61ac8f1ae2f29b7535aa7bb2d84f3030d2ef569e48577b8037eaa903bc1","target":"record","created_at":"2026-07-04T17:15:41Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"d41e0b1e1d638fd21d9f1d4c2cd6cff2f096cc1041b9d8d33fb0aaa801c4616b","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2005-06-29T03:58:45Z","title_canon_sha256":"4ce3084ecc94057b0a204913f68711f9a5a51049f80b557ce7a32ffdebe372a8"},"schema_version":"1.0","source":{"id":"astro-ph/0506713","kind":"arxiv","version":1}},"canonical_sha256":"9706e9ad45ba8c7766aafa134326ac60da230c98caf541494d93263f3e386a9c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9706e9ad45ba8c7766aafa134326ac60da230c98caf541494d93263f3e386a9c","first_computed_at":"2026-07-04T17:15:41.657188Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:15:41.657188Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZMsdw2LOMWB5e64/NYWiDmtz2XhxUe8oaD3/CpiAPvs9KctJk71nsAyKyrfuenWMstx3lD3BFuuEICVaJfKsDA==","signature_status":"signed_v1","signed_at":"2026-07-04T17:15:41.657631Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0506713","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0a52e61ac8f1ae2f29b7535aa7bb2d84f3030d2ef569e48577b8037eaa903bc1","sha256:784a8e42882934ae417ef60a1e54fc6e0229c1e24dbe70b451c2599462c10f62"],"state_sha256":"6019380aa1e9f4a5e8d6fae2be809510ddd37dd3e4939a1a0fe214d7f873ad08"}
