Visual concealment can involve background matching, disruptive patterning and behaviour. Effectiveness depends on lighting, viewing distance and the observer's sensory system. This activity isolates colour contrast with simple patterns. It does not turn an animal transparent, simulate natural selection within one individual, or calculate a trustworthy detection probability from a small set of display colours.

Drawn imaginary moth and controlled backgrounds; no real detection percentages, evolution rates or survival scores.
What to look for
- The same animal can contrast differently
- A body remains present when hidden
- Reveal outlines are teaching aids
Explain what you noticed
A white winter bird remains white after snow melts, exposing dark ground. What is a plausible change?
Keep this idea: A useful pattern depends on its background and observer.
