The road uniforms must have had light-colored caps, and the home uniforms must have had dark caps.

In 1902, the light-colored caps wore worn at home. The group photo that we've been discussing was probably taken at the Polo Grounds, suggesting that the players were wearing their 1902 uniforms for the pre-season exhibition game.

That would explain why the caps appear to be plain white in the pre-season team photograph for 1902 but with a variation, the 1902 caps on the uniform database appear to have red rings and are not plain white.
