the claim

Bulls are colour blind and cannot see the color red.

the verdict
INSUFFICIENT LEANING
Recorded sources
3 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that bulls are colour blind and cannot see the color red?

Unclear. Two lion-focused items state that lions lack red-sensitive cones and cannot perceive red hues, and a 1928 newspaper item says a red rag appears grey to a bull. None of the placed sources directly establishes that bulls are colour blind across the full spectrum, so the evidence covers only the red-blindness part of the claim.
