Relative advantages of dichromatic and trichromatic color vision in camouflage breaking

Lay Summary Online camouflage games reveal trichromats are better at finding birds and eggs than simulated dichromats, but dichromats can learn faster. Color vision varies markedly between species, such as between dichromats with 2 different color receptors, and trichromats with 3. Contrary to expectation, trichromats captured the nightjars and eggs faster than simulated dichromats, but simulated dichromats' capture times were affected less by a number of camouflage variables, and they learnt to capture eggs faster.
