How to Describe Color in an AI-Colorized Family Photo
By ImgHeal · Updated
A reader may need to know what a colorized photograph looks like without being led to believe its colors were recorded by the original camera. Describe both the viewing version and its limitations clearly.

Identify which version is being described
State whether the displayed item is the source monochrome scan, an AI-colorized derivative, or a pair of both. Compare any color statement with the original source and independent references. A blue coat visible in the derivative is an observation about that version, not evidence that the real coat was blue. Keep known colors, remembered colors, and generated choices distinct in the accompanying record. Avoid letting the accessible description sound more certain than the visible caption beside the picture.
Mention color when it contributes meaning
Choose colors that help explain the presentation's purpose, such as contrasting garments used to distinguish people in a group. You do not need an inventory of every shade. Describe generated colors as features of the colorized version, and put the broader disclosure in readable surrounding text. If a historical color is supported by a separate source, cite that evidence in the caption rather than implying that a visual model verified it. Use names or numbers as well as color when identifying people or regions.
Review the description after color changes
Check the exact exported image, its alternative, and its disclosure together. If a new colorization changes the coat from blue to brown, update any text that uses the coat to locate a sitter. Review the source monochrome version's alternative separately; it should not acquire colors that appear only in the derivative. Ask whether a reader who cannot see the comparison can still understand what was recorded and what was interpreted. Preserve the unedited scan so future versions do not lose their point of reference.
Check before sharing this record
- Name the source or colorized version explicitly.
- Do not turn generated colors into historical facts.
- Update identifying descriptions when the colors change.

Questions about this restoration task
Is saying blue coat in alt text always misleading?
It can accurately describe the displayed derivative when that version is clearly labeled. The problem is presenting its generated color as a verified fact about the historical scene.
